Yeah, and the overheating problem is lame too, but it doesn't really happen for me. If you are smart about it you can avoid the problem by just putting it on it's own to the side of the TV or something. As long as you don't cover it with things and give it fresh air it should be right.
Wireless internet, yeha, you can buy an adaptor for it which is lame, cause it is expensive, but luckily enough my entire house is networked =D that and wireless internet sucks anyway, lol, sif not cable
HD and Blu Ray, well yet again you can buy another lame attachment for HD but not Blu Ray. PS3 got it on 360 that it's actual hardware definitely got some perks over the 360, for me I don't mind but cause I just like the 360 better. The controllers don't make me want to develop a terminal illness every time i use opposed to the PS3 and I'm too friken poor to afford a TV that you can actually tell the difference between HD / Blu Ray movies and normal DVDs (lol). But yeah, the DVD file size limitation is lame for 360s, that is definitely one huge plus for PS3 and I've seen articles of some game makers saying this will pose a problem, but hey, the games they got now on 360 DVDs are friken amazing in my opinion and HUGE gameplay so I don't mind too much. I'll just wait for the xbox.... 720?
It really just depends on what you find really important to you in your system, if it is for use as a Blu Ray player or a console, cause if blu ray isnt important to you then it really doesn't have any sway over choosing a console, but sure, if you got it, it is good =P
Good luck in choosing what you want mate
