Well, I think I'll be exclusively on Vista for the next year at least. Quite frankly I don't have the money to upgrade all my machines. I'm real big on legal software, so I won't pirate it except for testing and learning purposes. On top of the fact that I have no money, Windows 7 significantly complicates networking with "Home Group." I have yet to successfully network a Windows 7 computer into my Windows Vista exclusive (well, except for my mom's G5 Imac) home network. Networking is so EASY with Vista. It's certainly a thousand times easier than XP. Windows 7....let's not even go there.
The problem is, Microsoft dumbed down networking so everyday users could use it. You can no longer just access computers by typing in their username and password. Now you just have 1 password for all computers on your network (this is REALLY insecure BTW) and it has to be some wacko 16 digit password with capital letters, numbers, and symbols.

I'm not gonna lie here. ALL my passwords are exclusively numerical and range from 5-27 digits, so this complicates things considerably.
Nah. Windows 7 just isn't for me, especially since MS finally fixed Vista so it's decent. I'm sure some hacker's gonna reprogram the networking part of 7 and distribute a cracked version of Windows 7 online. Then I'll just remove the cracks and activate it legally. My computers are too interdependent on one another to not have them networked together. I like being able to make or download a file on one computer then be able to access it from any other computer on the network without even having to transfer it.
I also can't stand the control panel in Windows 7. It sucks so badly. They got rid of classic view. Okay, I've been using classic view since the Windows 95 days. The category view was bad enough, but at least you could put it back to classic. Now they've got like these tiles that you can't change to classic and they just don't work for me.
Windows 7 is a great OS, but they should have left networking to the experts and kept the classic wonderfulness view in the control panel. I also don't really like the new taskbar. I like being able to see what my open windows are called. Just having one huge icon is pretty useless. If you can't see the icons in the previous operating systems, you must be blind.

: It looks slick, but most of it I'll never use. I'll stick with Vista till I can get a new way of networking with Windows 7.
