We have a few in the office.. it's has a propetary usb charger/data cable.. but you can power it with a usb port so no worries.. 
the wall charger is separte.. but I think you can use any usb wall charger..
Device is nice.. I personally have an iPad 2 which is a bit snappier, but the galaxy tab is a fine device.. I only don't like the plastic.. much prefer the aluminum from the iPad.. feels a bit sturdier..
Flash support and website are overal better looking on the Tab compared to the iPad, First party Apps are great (email, youtube etc) Third party apps are horrible, get if you can the optimized versions for the Tab.. the Tab is a bit on the long side so I can't use my thumbs in the center of the device in landscape mode.. but it's a good device overall.. If I wouldn't have an iPad I would have gotten the Tab and believe me.. we have around 10 tablets in the office and it's the best android tablet out there.
