There is no doubt about it, SSD's are extremely beneficial for a boot drive. They are prevalent in any new computer build these days, and pretty much every custom PC you would buy from the store. I won't bother citing sources for this one, because the results would be very numerous.
As for the longevity aspect of it, yes some SSD's have been failing... but so do conventional mechanical hard drives. I have yet to see any statistics proving that SSD's are failing at a higher rate than mechanical drives, they just seem to be getting bad publicity. Do your research on the different types of SSD's, Sandforce, Marvell etc.. OCZ Vertex drives have a pretty bad rep right now, but quite honestly my OCZ Vertex 2 60 GB SSD has not caused me any grief.
In regards to SSD longevity, I don't think were are at a point yet to determine that. Based on SSD specifications, yes they do seem to result in a slightly lower lifespan but if you maintain your SSD properly you should still be able to have it 5+ years without any problems. I say we aren't yet at a point to determine this, because most sites/people haven't had an SSD for that long yet.
Anyway, the short of it is... SSD's are extremely beneficial for a primary boot drive. Be careful in deciding on your capacity however. I would suggest a minimum of 120GB, as the 60GB will be essentially filled up with Windows and a few critical applications I'm sure you will have. It's best to keep your SSD with a bit of free space (do some reading on the sweet spot) so you don't want to be overloading the thing.
