i think you made the right choice. either way you still have a shiny new mac. and unless you really need a laptop as ridiculously thin as the MBA, you should go with the MBP. more power, more customization/upgrade possibilities. if you really desire the MBA's startup speed and solid-state benefits, then remove your MBP's dvd drive, and replace it with a solid-state drive big enough for all your applications and OSX. then you'll still have your regular harddrive for storing stuff, but the new SSD for quick startup and app opening
