Really interesting. I went to the Apple Store yesterday to try out the different Macbooks and yeah, all the font sizes felt the same. I'm not sure what to think now.
I got the 13" MB Pro in yesterday, so I played around with it last night and did some comparisons. The font size is bigger in most instances on the 13" pro due to the lower resolution. There are some apps where it isn't very noticeable, but on most it is. The font is also darker in most places, which makes it a little easier to read for me.
Overall though, I am undecided and will need to spend a little more time with each machine before I decide which one to send back. For your information, I will post my personal pros and cons of each machine at the moment. I know for most power users, they would disagree with these... but these are coming from a casual user who just needs to be able to work comfortably.
MB Pro 13" pros
-text is easier to read in most instances due to being slightly larger and darker
-easier to type on for long periods of time due to more feedback on the keys, good for paper writing
-color is more intense
MB Air 13" pros
-obviously it is lighter which makes it easy to rest about anyway when working on the couch. Although, the pro is by no means heavy.
- i do like the wedge design for comfort when typing
-it seemed to be cooler. The MB Pro got hot pretty quick
-much less glare
Overall, the Air does look slicker... but I really need to weigh that against my comfort in using it. My two main hangups are text size and also the shallower keyboard.
I have a paper to write tonight and tomorrow, so I am going to play with them more while doing that and try to make a decision by Thursday on which to send back. I really want to like the Air the best because it seems more cutting edge, but just not sure yet.
