I was going through this with one of the guys at work, running a VM on his MBP and it was slow, so we looked at upgrading him to a SSD. The dealer I get all my apple stuff from at work said to be careful as there's only a handful of brands that will let you upgrade the firmware in OSX without a pain. With SSD's, being able to update the firmware is a big thing for reliability.
That aside, it's going to be a million times easier and less of a hassle to do now as opposed to later.
