I know it doesn't add a ton to the conversation to share an anecdote, but this conversation is really interesting to me right now. Tomorrow my new Asus Q325UA arrives, shipped from Best Buy. If you've never heard of the Q325UA, or have trouble finding reviews online, that's because it's the Best Buy version of the Flip S. In theory, it's very much the same machine, though I'm not sure from reviews if the Flip S typically ships with the sleeve or Asus mini dock - the Best Buy version only includes the Stylus. I'll find out the software situation tomorrow... and we'll see how the hardware does.

ETA: With a little research, I believe the primary hardware difference is SSD. SATA in Best Buy version, PCI-e in the Flip S.
