As of this morning I was set to go forward with the purchase of a 13" MBA i5 with a 256GB drive and 4GB of RAM. I was still pondering the 13" MBP, but considering the fact that I travel for business quite a bit the MBA is attractive. My typical use involves using the Microsoft Office suite, particularly Word, Excel (lots of spreadsheets) and PowerPoint, as well as receiving .pdfs that can be somewhat large. Then I decided to chat with someone at apple.com. After describing my typical use, the person on the other end of the line recommended the MBP because its processing power and storage are more conducive to my needs. They stated that the MBA is better suited to light uses. I was under the impression that the MBA could handle all of the above and then some. Any thoughts?
