Yeah, waiting makes some sense, really ....
That was one of my original points I was trying to make, I guess. Even though I forked out the money for a 512GB SSD for my Macbook Pro last week, I did so only because I went with a Toshiba with Apple's firmware on it. My thinking is, if this specific configuration was good enough for Apple to ship as an option on new systems with OS X Snow Leopard, then it should be good enough for me to use as somewhat of an "early adopter" of SSDs in Mac portables.
Unfortunately, this drive isn't one of the faster models out there, AND there's at least some evidence that its firmware does a lot of background reorganizing of data stored on it, in an attempt to compensate for lack of TRIM support in OS X. This is likely BOTH while Apple chose it for current shipping systems AND why it may not have the lifespan or performance of models that don't do this.
It looks like many of the other SSD options out there still have various firmware issues that need to be sorted before they'll behave 100% well with OS X. (Heck, that's still true for Windows with some of them! I'm fighting right now with a 128GB PNY "Optima" SSD that seems to randomly corrupt data in Windows 7 every 3-4 weeks or so. A quick Internet search revealed another guy who reviewed one, saying he was having the exact same issues with his -- so I'm suspecting a firmware issue more than just having a defective drive.)
If money was no object, I'd likely buy a Mercury Extreme from OWC for my Mac, today. It may have some issues with waking from hibernation mode on Macs, but I could turn that mode off and not really miss it. In most other respects, they seem to be highly rated and FAST options for Mac users, with a potential advantage of getting better support by way of future firmware updates. (Some SSD makers seem to pretend OS X doesn't exist. OWC has a vested interest in caring.)
But otherwise? I think summer isn't THAT much longer to just hold out and see what OS X Lion brings to the table. Better TRIM support would at least get you much more "on par" with being able to choose whichever SSD a Windows user found to be a "good, reliable performer" - vs. having to worry about special limitations of OS X.
