get a 5600, Ive had both the 5600 and the 5000 and I tell you its worth it for just the extra battery life.. By my 3rd class the battery would be dead on my 5000.. my 5600 has gone thru all 3 of my classes, lunch and several hours of mp3 listning today and battery says 50%.. the 5000 has the same battery as the 5500 btw so I would expect it to suck that thing dry just as quick.
