The best? Yes a bit!

So the new tablet Samsung also available in Samsung Galaxy Tab 7 SM-3 T2100ZWAXEF Touch Pad 7 "(17.78 cm) ARM Dual Core 1.2GHz 8GB Android Jelly Bean 4.2.1 Bluetooth WiFi 8 inches White Samsung Galaxy Tab 3 SM-T3100ZWAXEF Touch Pad 8 "(20.32 cm) Dual Core 1.5 GHz ARM 16 GB 4.2.1 jelly bean Bluetooth WiFi Blanc.

The 10.1-inch model closely resembles the older generation, slightly thinner and lighter. The grip is always as good.
In use little difference. The set remains fluid and if coming from the galaxy tab 2 we will not homesick.
In terms of autonomy I have not found any glaring difference either. It is always good anyway, no problem at this level.
Some small additions that do not revolutionize this new version in the end.

Found against by the ability to recharge the tablet on a micro USB port thanks to its PC. Also the installation of an infrared port that will include transforming the tablet into a remote control. An addition to my major sense and very interesting!

In short, what has been the success of version 2 can be found here. Little change in the end but it is in my opinion a very good tablet. Once we have the 2 to the 3 passage might not be necessary unless you want absolutely the usefulness of the infrared port.
Otherwise autonomy, screen quality, fluidity, ... everything is good! Too bad that Samsung has just moved the speakers on the sides rather than forward as the two which seems more natural.
