Alright, so I plan on getting an MBA 1.8/80 HDD. I plan on running just the simple stuff like M*crosoft Office, Photoshop CS3 (not crazy, but just some minor photo editing for school projects) and it's for web/e-mail etc. I was thinking that I will be buying an External Hard drive because of the lack of capacity. Now, do you recommend partitioning it so it is capable of doing both Time Machine and extra storage? Or do you have other suggestions?
