Summary: I've tried and used almost all the name brand 10 inch tablets on the market and I rank this near the top of the 1st generation ones that came out. Way more responsive screen than Toshiba Thrive, Motorora Xoom, Acer Iconia, and Sony S. Internet connection is very good and very fast. The negative side is that this unit has no HDMI or usb ports (although you can buy a cheap connector for their proprietary port that allows for connection of external drives and accessories...
Summary: I could not tell a difference in it being refurbished...last I looked they were out of stock...this would be an outstanding christmas gift for anyone...I had a hard time getting the drivers for my pc...I called the referbisher who then told me to call samsung. Both were helpful.
Summary: I recently purchased this ( 1 week ago) Galaxy GTP7510-UW32ARB. The box arrived in good condition with charger, USB cable and instructions booklet. I charged the unit overnight and started using the unit. The auto rotation (of the screen) function works only some times. The back of the tablet gets hot when the unit is used for more than 2 continuous hours.
Summary: was skeptical about a refurbished tablet...WOW!! can't tell it was ever unboxed.While 3.1 is not the most current os, it does an excellent job on this awesome tablet! strongly reccomend this samsung to anyone who wants a great deal on the only real alternative to the ipad!!
