So, I'm getting an 8gig ssd for my Eee from one of the guys on the eeeuser forums... I'm pretty sure it will fit right in on top of my internal SDHC reader mod. This will give me:
-4gb main SSD
-8gb Second SSD
This should be enough storage for me, as I have only been using my external 80 gig drive for music and videos. I will be able to mount all my ebooks and such on the 8gb along with all my setups and whatnot, which should give me the opportunity to travel even more lite.
