I'm getting more involved in mobile development - and I need to be able to do work for Android and Mac - so that means I'll be picking up my first Apple machine this year. I'm still trying to decide if I'll get a Mac Mini or a MacBook Air.
I'll need to make up my mind by February. Reading that you like yours helps me feel a little better about it. If I didn't need to be able to build stuff for iOS I wouldn't be buying one.
The video issue with this Linux box is fine. It's a very inexpensive Acer with a pretty small case so I new my expansion options would be limited. I just wish Intel sold video cards because if they did, I would be all over that.
