One minor quibble: as far as I can tell, Apple is actually mostly shipping drives manufactured by Toshiba, which don't seem to be rebrands of Samsung's tech. The way to tell is to look in System Profiler; Toshiba drives will be labeled "Apple SSD TS128" or "Apple SSD TS256", while Samsung will be "Apple SSD SM256" (they only seem to show up in the 256GB option, and even most of those are Toshiba).
Anyway. I recently picked up a new MacBook Pro and went for the (256GB, ended up with Toshiba) SSD option, and I've got to say I don't ever plan to go back to a mechanical drive if I have the choice. It's not just the flashy-but-pointless things like boot time or first-time application launching. It's the fact that most of my life consists of reading, paging and grepping through lots of files, and that is stupid fast with the SSD. I don't worry too much about write performance, because typically I'm in an incredibly read-heavy workflow.
