So I went wild and went outside of my budget, $1189. And got the MacBook Pro. Saying this, I know that BackTrack boots and works on my MacBook (less then a year old and gave it to my wife, aren't I so nice). Also the battery life which is 7 hours, though i think thats a reach, and you have to have everything off. So I think 4-5 hours wont be too far of a stretch. Also the backlit keyboard and touchpad are really nice. The only downside is the intel graphics card. I hate myself for getting the 13'' with the on board graphics. But in the end i don't need something im going to game on that much. (Though I can play CS & a few other Valve games.)

@nihil BT was (a) absolutely essential to me. Otherwise I would have kept the Asus and lived with the battery life, but not having an injection capable laptop on a $1200 computer is outrageous, i have no idea what Asus was thinking. Though I don't think most gamers spending $1200 on there laptop really care about it. But for me its something i really would like to have.

On the downside about the mac, #1 is price unless you make more then minimum wage and then a lot more. It's likely not really worth it. Unless you have other reasons to do it. (I also do web design and PHP, and i feel inspired when using my macbook and so it was something that was an added touch.)
#2 The price
#3 Right click ... jk just change the settings. And you gets lots of other clicks (gestures).
Though other then that I can't really think of many, but i really do like it, and think its worth the money. Though I think this thread is a really good resourse for others who have laptops and want to look at cheeper solutions. And we should keep this going with more options and cheeper ideas, though i know some will want a pricy solution. So if you have the money, dont mind being called a fan boy and want BT to work a MB or MBP isn't a bad idea.
