Not that it's all I took away from this great article, but I'm wondering what I can do in the meantime to optimise my use with such devices.
Optimizing Linux with cheap flash drives

It appears if you want to run ext3 on a cheap flash drive, you pretty much have to assume that it's going to be slower than advertised (possibly MUCH slower, especially for write), and that there's a very real risk of wearing out some areas of the flash faster than might be expected. Probably okay for a mostly-read workload if you ensure that you turn off atime completely (or every read is also a write!), but not ideal for something with regular writes.
If it's an option for your use case, then sticking with the original FAT file system -- and using it natively -- is probably the least bad option. Certainly that's what I do with all my portable drives that see any kind of regular updates. (It also has the benefit that I don't have to worry about drivers for the file system on any system I might plug it into.)

I may as well switch to just FAT32 for part of the use cases and the other ones are dominated by reads, so can stay on ext.
