Hi everyone I'm going to get a macbook air for the obvious advantage of it being portable. I can't decide if it should be 11" or 13". I mean 13" is great and just enough for screen size (i'll be watching tv shows and stuff too) but i can't be sure if it's portable enough. I want it extra portable cause i will be going to meetings with it a lot. I will be using it for my work too and i work for Google's Adwords advertising part. So i will be using safari a lot. I can't be sure if 11" screen will be a nice surfing experience because of the resolution and lack of screen real estate. Can you give me a hand here? Which should it be? Also i am really confident with all the MBA models' processers but i can't be sure of the RAM. People everywhere are saying Lion uses more Ram and i don't want no lag on my computer.(this will be my first mac too) Also i will be using it for 3-4 years. So i want it durable, powerful enough so i can do things i do. And i don't want too much power because i don't do no photo, video editing or stuff. I watch tv shows, use it for the job, power point and excel use a lot obviously. I don't crave too much power but i can't be sure if 2 gigs will be enough. I need your advices, all advices appreciated, thanks.
