Well..if you are going purely by the looks of it..i feel Revolution is best.
The PS3 looks bulky and huge...i am not sure how it scales to the PS2 but it seems like right now where my PS2 is, wont fit a PS3 as easily..and things will have to be moved. So i hate its size...at least from what i see, maybe if i had a side by side comparison i can make a better judgment. Just seems unnecessarily large...is it going to have multiple functions too? I mean PS3 + scanner + printer + toaster + router? >_> I dont know...unless theres a GOOD reason for being huge...i like my consoles reletively small.
Xbox..i dont konw looks like those more compact computers...just doesnt seem to fit a console look at all, i mean as much as i dont like PS3's bulkyness, it at least resembles a console somewhat..this thing is like...dang O_o *pukes*
Revolution! I like it so far, its slim, sleek, and very easily put into any pace at your whim. I like its smooth exterior and blue lights make it look kinda...cool i guess. That, and also it has multiple colors ^^ i might actually get a colorful one...i was so disappointed when GC didnt release their orange one here leaving me to get Black. ; ;
So Nintendo for the win on looks for me.
