I think the problem is not Bootcamp or OS X, but Windows Vista itself. I did a quick google search and it seems Vista (maybe even XP aswell) is not designed to work efficiently on SSDs.
SSDs are not too common, so it may be a while before Windows can run smoothly on them. I'd guess Apple developed OS X to run on them in new macs
Is Solid State worth the cost? I looked them up quickly and I got the impression that they are stronger, more durable to impact, but they don't last as long. They cannot be written to or read from as much as a regular HDD.
