Have had the blackjack for a month or so now, and it's pretty ok in
general, but the battery life sucks. Lasts about a day and a half,
then quickly enters the spiral of death -- complains bitterly about
being low on juice, then SHUTS OFF THE PHONE without telling you it's
off, so you get no calls and can't place them. Then it
unceremoniously shuts down completely. No wonder they give you two
battery packs... but who wants to lug them around? And the "holder"
for the spare battery is a hilarious hack of an afterthought -- a
plastic box that the (lame, incompatible with anything else) plug
goes in. The box could hold 2 batteries, but charge only one. Lame.
