I’ve been using a Macbook Air from 2012 for the last year and love it in general. Our Wayland High School is “loaning” them to every high school student as part of a 1-1 program. It is a sweet machine, but I’m learning it does have it’s limits.
The big limitation I’ve hit with my Air is fan noise when doing anything with video or screensharing. GotoMeeting, WebEx, Skype, all of these get the CPU fan spinning to maximum. While this isn’t technically a problem, it is lowering my satisfaction with my Air being my only computer. And for reference, I’ve got the Core i7 version w/ 8gb RAM.
I’m hoping the next generation of Macbook Pros with Haswell internals will be powerful and have great battery life. I’ll probably upgrade and pawn off my Air on one of my kids. Don’t tell them I said that.
