Has anyone switched from the Pro 13" to the Air 13"? And if so, can they speak a little about the experience? I know in terms of general, every-day use, the Air suffices when it comes to processing power, etc (presumably even more so after the rumored refresh this summer). I'm considering switching, but I'm particularly worried about about the higher resolution. Yes, everything will be sharper and there will be more screen real estate (both of these I'm very attracted to), but I worry about font sizes. Has anyone gone to the Air and regretted it or felt the font size made it very difficult to read? Was it a smooth, easy transition? Or did your eyes strain from smaller texts? Thanks. EDIT: I've posted a similar thread over at the dedicated Air forum. I'm proposing the same question here to see if I can get more feedback.
