I grew up a console gamer, always having a pretty crappy computer around. I'm used to the controller, and I'm used to the variety of genres. However, not only do I have no interest in having to constantly upgrade a computer (near impossible since, at the moment, I'm using a laptop), I just don't want to deal with the driver issues, patches and so many other nitpicks that come with it. The demo for UT3 basically just made me say "enough is enough".
When it comes to handhelds, though, I like the innovation of the DS and some of the things they are trying to do with it, but I can't justify owning one. I got rid of my system because either the good games lack replay value (Pheonix Wright), or they are limited in A.I., physics and other capabilities compared to consoles. They're nice once in a while, but I've played those sorts of games already. Plus, it doesn't matter if it's all done with a stylus now, the latest Zelda is still played like a Zelda. The input device hasn't made that much of a difference.
So, in the end I stick with console, as that's where the technological innovations are being made, providing truly new experiences as opposed to old experiences with a new input device.
