I am torn between the MBA BTO to highest specs and MBP 15" 2.2GHz QCi7. Basically, I used my penryn version MBP 15" for work and home use. Usage: 1. Workfront : MS office suite Parallels for Siebel usage (crappy corp don't use salesforce.com) 2. Homefront: Adobe CS5 Adobe lightroom Internet/flickr/forum/blogging MEDIA conversion to iPad/iPhone screening Video editing I love the big anti-glare screen on 15" and easy on the eyes for photo PP. But I've been lugging a 15" for 3 years and it would be superb for dropping the weight if I go for MBA and iPad daily. (am a lady btw ^_*) So should I: A. Buy the MBP 15" and get the performance for my needs B. Buy the MBA 13" and get the portability, while hoping I save enough for Ivy Bridge in 2012 c. Wait for Ivy Bridge and hope apple change of form factor and lightweight enough for MBP.
