Hi guys, i want to buy a MBA but i have some concerns. First, how is the speaker ? I watch a lot of movies on my laptop and i don't really like to put on headphones everytime i watch a movie, so i would like to know if it's ok for that purpose. Second, i only do normal stuff like web browsing, watching movies, music, chat, office... I don't really do heavy stuff like photoshop or video editing, so i would like to know if the 4200 rpm drive will really affect the speed during these tasks ? I really appreciate your help and i'm sorry if this has been ask a million time. PS : Sorry for my english i'm a french canadian !
