What the hell?? Are you trying to start a SVR4 vs BSD vs Linux war now??? Also... Atari was better. In my case, because of the Galaxy Tab's 7-inch form factor--which fits easily in everything from my trouser pockets to the jacket pockets without any modification--I bring it and use it everywhere and it literally gets used FAR more than my cell phone and runs all the same applications (even the ones I already purchased)... which leaves my phone free to be a phone more often than if I didn't have my tablet. ...so, it CAN replace it. It just depends on the individual, form factor, compatibility, support and so on.
