This may be a dumb question, but I'm wondering if flash drives are system-specific (e.g. do some only work with Windows, are some better for Mac) and also if some are better for storing audio and video files than others.

I'm looking to buy one or two more, with 4 to 8 GB capacity, and some look like great buys (e.g., 8 GB for $20), but I'm not sure if they're all formattable for Mac (OS X or OS 9). I also don't know if any manufacturers are known for making problematic flash drives.

I could research this on 'puter sites, but I'd have to set up accounts and probably wade through a lot of geek talk before getting an answer, and I know some of you 'cats (like Amos) are geek enough to give a quick answer or at least opinion.

Overstock.com has an 8 gig flash that's available for $1 shipping, $19.95 for the drive, today only.
SanDisk 8 GB Cruzer Gator USB 2.0

Any opinions?
