Alright. So, I'm turning sixteen and my mom is giving me a choice of MacBook Air and a MacBook. Personally, I like the look of the MacBook Air, plus the portability would be nice for any traveling I might do. But, my main issue isn't with that. I need to know how well the air would run. I generally have several programs running at once (I currently use an older Imac, 2006/7 or so.) I generally have photoshop (cs4), Itunes, Aim/MSN and maybe a download or two running at any given time. Not to mention I run flock (internet browser, comprable to Firefoxruns on the same platform.) and surf the web for twitter/tumblr/facebook/ect. Not to mention I'm constantly saving things to my computer, though USB drives and an external hard-drive can be used to save things later on when I need it. I need to know if the air is practical in this situation, or if I should go with the regular macbook?
