So, I picked up an Acer W500 to have an x86 tablet to play with while waiting for Windows 8 to get all official on us and, within its limitations, it has been great.
I started looking up options to increase the size of the 32 gig mSATA SSD (I already added a 32 gig SD card) and the only real option looks like this one:
$159 for 120 gigs, which isn't really bad though I don’t know if it is worth it since the RAM is soldered on the board, so you are stuck with 2 gigs, with part of that going to the video card.
I think I am just going to wait it out, I am betting on medfield tablets running windows 8 (arm power envelope, full x86 support). I like the idea of ARM, but I don't know if I am ready to give up x86 quite yet.
Here is one running ICS: http://www.engadget.com/2012/01/10/intel-demos-lenovo-made-medfield-tablet-running-ice-cream-sandwi/
