I have been pondering getting a MBA instead. I have an early 2011 MBP 13 base. Great machine. I have no complaints, I just find that I don't work on music anymore, which was the only reason I opted for the MBP over the MBA. I take my MBP with me everyday now to work, which I wasnt before and the thought of a lighter machine is enticing. Indulge me here, I know this is the MBP forum, but I guess I wonder if anyone else feels this way. Again, its a great machine and Lion runs very good on it. I had been thinking of jumping up to 8gb or ram and then going to a ssd. I figure these additions would be worth the cash and then was looking into a TBD later this year. Obviously, selling/trading the MBP for a MBA would kill some cash and probably push back the purchase of the TBD. And I do like the thin, tapered design of the MBA's. When I buy a Mac, I expect getting at least 4 years out of it, and I could go and buy a MBA right now, but I am working hard on saving money so I do not want to do that (I'll be moving this summer). Any thoughts?
