Leo forgot he was going to talk about the Kindle 2 but still manages to come up with something cool. It's the Coleman Flashcell Rechargeable Screwdriver. Just a cordless screwdriver, but it's the charging of the battery which is exciting. The charging base uses ultracapacitors (currently an EEStor project) which give the battery a full recharge in 90 seconds, which will last the screwdriver 30 minutes. It's the first and only commercial product available using this technology.[play video]
Leo even manages to demonstrate the charging of the screwdriver, and keep it running for half an hour. Just ignore the clock behind Leo.

A Message from the Kindle 2
Al Spalding from Acworth, Georgia refers to the voicemail from the Kindle 2, played on Buzz Out Loud, in anticipation of Leo's review of the new Kindle. A protest against the objection by Authors' Guild to the Kindle's new text-to-voice feature.
