How would you change Amazon's Kindle (2011)?

Amazon's Kindle is, broadly, the million-selling gold-standard that all other e-readers aspire to. This year's edition was slashed back to basics, with the hardware keyboard, touchscreen, expandable memory, 3G access and MP3 support sacrificed in favor of a $79 (with ads) price tag. Now you've had three months to get to grips with the changes, do you feel it was worth it? Do you miss the keyboard, are the adverts too intrusive, is it the right size for comfortable use? If you were in Jeff Bezos' shoes, let us know what you'd have done differently in the comments below.
