I've got a mid-2010 MBP with the 2.53ghz C2D, 6GB RAM, and have been watching the speed tests of the new MBA with great interest. Should I: -Keep the MBP as-is? It's definitely not lagging in speed at all. -Pull out the optical drive and install a boot/program SSD? -replace with a 13" 2.13ghz 4GB MBA? the last two options will probably cost me about the same, all said and done, depending on how big an SSD I'd get. Mostly used for web, mail, iWork, Office, some Windows 7 (through Parellels), iWeb; might be using iMovie more in a few months.
