DO NOT GET AN APPLE!I'll let you in on the dirty little secrets of Apple right now. There's no "evidence" of what I'm saying. Only my experience as a computer repair technician. I see 10+ computers per day so I know what I'm talking about. Let's begin. Oh but before we do, know that if any apple fanboys are reading this, they're going to be offended. Sorry about this, but these are just my observations. Let's get this over with.
Let's go back to 2003 and before. Apple made the best computers (reliability wise) in the world. So few viruses you could count them on one hand. Hardware that was 10 years ahead of it's time with reliability that could (and does!) last decades. A software that was limited but great for people that didn't do much. But all that changed in 2004. In 2004 they started signing contracts with third party companies in Taiwan and other obscure places in the world to lower their costs. The results were disastrous. The first victim was the all in one Imac G5. It had capacitors made in Taiwan that blew in 12-18 months. Now capacitors are little voltage regulators on a motherboard that help everything on the motherboard to function. When they blow, you'll get strange problems such as video, hard drive, ram, and other severe problems. Most of the time the computer just wouldn't even turn on. Or would turn on then turn off automatically after a few minutes/hours.
Apple's response to this was to issue an extended service plan for a total of six months and not tell anyone about it. In effect, they did absolutely nothing about it. They just did what needed to be done so they couldn't be sued. Then came the Intel based Imacs a few years later. SAME PROBLEM! Even if you buy a brand new mac today it will have this problem. APPLE DOESN'T CARE! There's a reason they charge you $800+ for a three year warranty on a mac. You're going to need it. Fuck. For the warranty on a mac, I can build a top of the line gaming rig. Just for the warranty!
There's only one way to fix these capacitor problems. Replace the capacitors on the motherboard, which requires a board-level repair which very few technicians do today. If you replace the motherboard for $1,000+ it will just have the exact same problem and go out again. Let's go with the Macbooks. The early ones starting in 2006. They all had battery problems where the battery wouldn't charge. It had something to do with the port replicator on the motherboard. If you replaced the battery it wouldn't fix the problem. Apple did nothing to fix this problem and the macbooks of today are still affected.
Now back in 2004 Apple was really hurting. They were losing business like crazy because their main target market were people that bought their computers for their reliability. So they had two choices. They could either make decent computers again and try to repair their image or change their entire business model. Unfortunately they chose to change their business model. Instead of advertising their computers as reliable, they decided to go after people that were really susceptible to marketing. In other words, people that could easily be "brainwashed" into buying their products. It's 100% true. I see it all the time. Let me give you a scenario.
Just two months ago some guy brought in a practically brand new Macbook Pro. It was 14 months old and had a bad motherboard. Now this was a $2,500 computer! I told the guy it would cost $1,100 including parts and labor to fix the unit and to my surprise, he said yes. So I did. When he came to pick it up I asked him if he was glad he bought a mac. And he said I quote "Oh yeah. It lasted a year. I can't ask for more than that!" What. The. Fuck. $3,600 a year for a computer. That's a good deal! These people are so far into the vortex of doom there's no hope for them. Ignore apple fanboys like that. They seem to have lost their minds. This is not an uncommon situation that goes on in my shop.
Unfortunately as a technician I have to have a mac in order to work on some mac problems. If I wasn't a technician I wouldn't have one. I barely use the thing and I've done more work on my Imac in the past 6 months than I've done on my custom built office master computer in 5 years.
Now what should you buy? It's simple really. Get a desktop. $50 is the max you'll EVER pay for a part.....even a motherboard! Unlike laptops which can cost up to 10x more to repair, desktops are really affordable. The going rate for replace in a motherboard in a laptop is $400 - $450. Motherboards for desktops are about $45 - $50. Another thing about laptops. They're absolute crap. 85% of my business comes from people with laptops that are less than 6 months old. 85%! You know why that is? They're just made like crap nowadays. Tell you what. Go head on over to Dell.com and try to customize a desktop. They try to throw a 3 year warranty in your face for $99. Now go try to customize a laptop. They don't even OFFER an extended warranty for a laptop! Why? Because they know they're made like crap and will blow up way before even the 1 year warranty.
Now let's talk about warranties here. Nowadays, laptops come with a 3 month warranty. I know, I know, it says 1 year on the box. Well I'm here to tell you, IT'S A LIE! If you get the computer home and manage to find the hidden warranty booklet stuffed between the cardboard and actually READ it, it reads something like this:
Limited *1 Year Warranty
See that little (*)? That's the clincher. Now let's get to the bottom of the page here.
*Turn to page 17 for more details
On page 17:
Limited 90 Day Warranty on the Following components:
Motherboard
Screen
All Plastics
Screen Hinges
Hard Drive
Optical Drive
Card Reader
WiFi Adapter
Battery
Keyboard
Mouse
Software
So in other words, the cord is warrantied for a year. If anything else goes after 90 days, you're just fucked. Now the number of things covered under the 90 day warranty varies for every manufacturer, but they all tried releasing computers that said they had a 90 day warranty on the box and no one bought them. So they decided to do it sneakily like this.
If you don't want to have to deal with hundreds of dollars in repair bills starting in 91 days after the purchase of a computer, you have to either buy a desktop or get a custom built desktop. There really aren't any other choices nowadays. I recommend just going and buying the cheapest piece of crap Dell or HP desktop there is. Yeah it will blow up in a year, but since it's a desktop it's not the end of the world. As I said, $50 is the max you'll ever pay for a part. If a shop charges more than that, they're ripping you off.
I have 4 laptops sitting in my shop right now with blown motherboards that are going to cost $400+ apiece to fix. One is 2 months old, another is 4 and the other is 5 and I've got another one I just found that I think is 4. DO NOT GET A LAPTOP!
These large corporations like Dell, HP, etc. would love everyone to switch to a laptop. Why? It's simple really. Before laptops, people were just like the OP and would keep their computers for 8+ years before replacing them. Now people have to replace their computers every 6 months or so, which could potentially increase these corporation's profits by 1,600%!
Oh, and I'm sure someone's going to come here and say "well I have a laptop right now. It's 5 years old and I haven't had a problem." Well they just started making laptops crap like this about 11 months ago so that doesn't surprise me.
One thing to remember is laptops were never meant to REPLACE desktops! Just like a pocket TV was never meant to replace a big screen TV. Laptops are meant to be used EXCLUSIVELY on the road. They are MOBILE computers! Nothing more, nothing less. And way too many people have been suckered into using these underpowered devices that are totally unsuited for their needs.
It didn't used to matter too much. Whether you bought a desktop or a laptop, you'd at least get a few years out of whatever you bought. it's not like that anymore. Trust me, I wish it was. People used to love me. They'd bring me their computers and I'd fix them up for almost nothing and they'd be VERY HAPPY. Now at least one person cries in my shop every day because their 4 month old laptop is now an expensive paper weight. My job is becoming very depressing.

This is where a laptop is suitable. Truck drivers, police officers, and other professionals that need to do their work exclusively on the road need laptops. If you're not one of these people you shouldn't own one. It's as simple as that. Another scenario would be if you worked between two offices on a constant basis. Let's ay you start work at 9am and need to move to office B across town at 1pm. You'd transfer your work from your office desktop onto your laptop and continue your work in the taxi on the way over to office B. Then when you got to your destination you'd transfer your work back to a REAL computer (a desktop) and continue working. These sorts of things are what laptops are for. Not as a replacement to your desktop.
