I work 3-4 hours with my MB. (I did buy it last summer, the one without the dvd-writer) I run a small webshop so i check my store, add products and stuff like that. When its "big things" like making product photos i use my Imac 24". So i run Safari and Textmate. Sometimes i watch and a movie while i work. I dont care about diskspace, my webshop uses about 1GB for backup, movie 10GB a few music files. I dont need a Macbook Pro, its to big for me. Sure i dont travel mutch, but i carry my Macbook with me in the house and in the garden I really like the new LED display. But is it worth the price? I cant say that i need a new computer really But well....i'm a geek! And sure i can afford a Air... Is the Air only for people without a MB, or is the screen/size worth a change?
