Color choice would be nice, I have seen some custom PS3s in red and white and some 360s in black, silver and white as well. I have not seen Wii in anything but white. I like my black PS3 though as it makes it look like a high end piece of electronic equipment and it matches my TV and SS system. Eventually there will be addtional color options on all of these before the next gen comes out. I am not really big on that sort of thing myself. Just what it can actually do. I chose my PS3 for the following reasons:

1 I have an extensive library of PS2 and PS1 games that I revisit from time to time and the PS3 will play all of them
2. As mentioned before it has the ability to play both DVD and Blu-ray fromated movies, as well as CDs, MP3s and MP4s this means my media set up only needs one device to play everything.
3. It has the most powerful processer and the deepest capability of any system ever made, it will take till 2010 before developers can get close to 100 percent of its ability.
4. Firmware updates allow for it to continue to be upgraded throughout it's life cycle for free.
5. The hard drive can be replaced by any off the shelf SATA PC drive which means I can download HD movies and TV shows as well as videos from You-Tube.
6. The only system capable of 7.1 surround sound.
7. God of War 3, Gran Turismo 5, Killzone 2, Little Big Planet, Home, Heavy Rain, Resistance 2, Metal Gear Solid 4, Drake's Fortune, Rachet and Clank Future Tools, Motorstorm 2, and many other games that no other system can do.

Like I said it's not for everyone, and for joe shmoe that wants the occasional party toy or basic game system the Wii fits the bill nicely.
