I think what this all boils down to "personal opinion". I've had my Wii since February and I've only got a couple of games for it but that what I reckon makes it so appealing. The concept and gameplay of the system. OK, fair enough the whole swinging of the Remote can seem a little gimicky but it makes a nice change to actually get a bit of physical movement out of a console. On that note, PS3 have ALSO implimented their own take on the Wii remotes' technology. Use of gyro-technology (or whatever techno-babble they named it). Twisting and turned the controller to steer, point/aim etc.
The whole, "integrating work and play" thing is a concept that was supposed to be apparent. The idea of finally getting up out of your seat and getting more physically involved (for some people who manage to destroy the room they're playing in, maybe not TOO physically involved LOL

: ). The dance mats where brought about by arcade machines. It was only once they were such a hit in arcades that the games and hardware started moving to home consoles.
For me, it's the games that matter more so than the processing power of the machine or it's hard drive space. I'm not strictly loyal to a particular name coz there are so many games that span all current gen consoles. As I've said before, I will probably end up getting a PS3 but I'm waiting for the games that I want. EVeryone's got their preferences.
Both consoles have their pros and cons. Waht seems to be overlooked is the idea that Sony is a multimedia technological supplier. It deals with TVs, audio players, stereos, entertainment systems, DVD-players so with the PS3, they've looked to implimenting the newest technology available into their console to appeal to a growing market coz we all know Blu-Ray discs and HD DVDs are the new media format for video and are fast approaching. Given a number of years, DVDs will fizzle out like the VHS. There are reminents around, granted, but it's no longer mainstream. The only think that shot up the pricetag for the PS3 was the inclusion of the Blu-Ray player. Sony are appealing to a much wider target audience.
Nintendo on the other hand are strictly for the games and the gamer's market. Their target audience is a lot more defined and "smaller" (for want of a better word). Hence the reason why neither the Gamecube NOR the Wii had dvd-players included. What's a gamer want with DVD player? If the gamer was ALSO interested in movies then by all means; consider a DVD player. I have a PS2 but I dont tend to use it as a DVD player. I'd prefer to use an actual DVD player than my console.
The reason why I reanimated this topic coz I wanted to see the responses now that all three next-gen consoles have been unleashed. But it appears that the major player in all this really is nothing more than personal preference. Maybe I was looking for a deeper motive but that's all it seems like from what's been said so far (no personal digs at anyone

). Interesting to see people's responses.
