I want to take advantage of the Amazon deal this weekend. I'm leaning going with the MBP because I happen to like the classic unibody look and more importantly I like being able to upgrade the laptop in the future without having to send it to Apple. I've been told on another forum that speed wise the MBA is more responsive than the MBP. Is that because of the SSD in the MBA? If that's the case would installing an SSD in the MBP even out the performance? I noticed the specs are slightly better on the MBP. Anyways i'm confused so I thought i'd ask. I do like that both have backlit keyboards.
