You know, I think I still am pleased, for two reasons. First, it has made a huge difference in startup time.
Reviews of SSDs always seem to over-emphasise the sustained transfer rate.
All SSDs have <i>seek times</i> that are a fraction of what you'll see on mechanical drives. That's the main source of the speed-up in booting, application startup, page in/out that makes SSD-equipped computers run so slickly.
I think the only thing to regret is, maybe, you could have got away with a cheaper SSD as you didn't need SATA III.
Also, I expect that I'll be in the market for a new MBP in a few years, so I can just order it with the cheapest HDD and then swap in this SSD.
Don't hold your breath. I bet you an internet that, in 'a few years' SSDs will be standard in all MBPs and the entry level will be at least 256GB, and probably not in 2.5" SATA form.
Also, the big unknown with current-generation SSDs is how long they will last in real-world use. No moving parts vs. the finite life of flash memory cells.
