Since last writing here,
The 64G SSD is has the nice trick that it includes a USB port (with a mutant connector) so you can just bit-for-bit mirror your internal drive to the new one, then pop it in to the mini-PCIe slot and reboot. (Linux even handles growing a mounted ext3fs, once you've made the partition larger underneath it - not a big deal since you're swapping hardware, and could just do it while it's still external, but if you forget, it's a nice touch.)
(For now I'm still using the 16G SD card [carried in a stick-sized reader] for my captioning efforts; if I had an easy way to put the EEE into mac-style external disk mode, I might use that instead - I could just sshfs into it, I suppose. Alternatively I'd use the phone for the same thing, but it's only got an 8G microSD, fast 16G don't seem to be out yet and wouldn't really be an improvement given that I keep a lot of other stuff on the phone's own card... would allow some direct phone-to-flickr posting, though, especially now that I have ASE to work with...)
