after 4 days...in fact with no use it was still at 78%
I just took a small trip to NYC...backed my power plug but forgot my stupid adapter at home

..crapped a twinkie figuring my unit would lose power and drain everything...I was playing with it a bit on the plane when I realized this( I was at 98%)..so I last charged at 12pm friday
Got it today at 1000am had 78% charge(I stored it in safety deposit box)
man was I pissed..I d/led subway maps, bus maps...I wish Dell had a universal adpater..I even tired quickly to find someone in NYC that sold the stupid adapter..why did Dell do that...should have been a port to just plug the power plug fro mthe cradle into the bottom...could have had both a sync connector and the pug port....darn them
Oh well just happy to battery was ok
any place beside dell to buy these adapters???
