How would you change the ASUS Padfone?

It's a phone, it's a tablet, it's ASUS Padfone! Possibly the maddest gadget concept we've seen in a while, this phone-in-a-tablet-dock is both surprisingly charming and surprisingly useful. ASUS might have rushed to replace the "half-finished" original version (the heavily redesigned Padfone 2 emerged a few months afterward), but let's talk about the OG unit here and now. What did we like, what we didn't, and what, most importantly, would you all change?
