I have an 880. I was fortunate enough to get a good one. Seems there was a lot of lemons out there for a while. Several complaints including batteries going bad prematurely and the unit itself not sitting in the charging cradle correctly. Again, I have had no such trouble with mine. That being said though, I would buy the newer One model as reviews are great. Better layout of controls, larger buttons, easier to read, and a touchscreen for events/devices. The one was not available when I purchased my 880 from Dell...$119 new limited time deal...I could not refuse at that price.
