I have (what I hope is) simple question regarding the MBA. I'm considering getting a MBA because of its weight (for portability), but what I'd also like to know is, how would it handle Photoshop CS4, video editing, etc? If not I may go for the MBP, but a part of me is leaning slightly towards the MBA because of its weight. Do any of you sometimes wish you had a DVD slot? How is the actual unit on one's lap when using it? I use my friend's HP and it almost burns my thighs sometimes and since I don't know anyone else with it I thought I'd ask here. Any input or suggestions would be appreciated, thanks.
