I have both a 13" and 15" MBP; I'm selling the 15" mainly because it is simply too large for traveling. I don't consider the 17" to be a portable computer; it's a monster size-wise and cost-wise...
The MBA displays are inferior to the MBP. I experienced significant eyestrain and a headache after using an MBA for 1.5 hours. I have never had that problem in over 15+ years of using Macs.
The only downside to the 13" MBP is the lack of an anti-glare display option from Apple. I solved it by using the excellent $35 Power Support anti-glare film. It doesn't introduce artifacts or color shifts like other films; it's appearance is remarkably similar to my 15" MBP with a matte display.
Another option is a $200 matte display replacement from Tech Restore.
