Unfortunately, the Launcher from Samsung (Touchwiz) steals pretty much from the very good performance of the hardware. Severe stuttering, as some reports, however, I could not tell. This in turn can be found at the magazine app. Since I in this but can not choose the sources and thus, for example, the hated Bild newspaper had in the reports, the app for me was already useless. "News Republic" and others are as much better.
Either way a Custom Launcher (eg Nova) ensures that even the homescreen works rats quickly without losing the features like multitasking or pen operation. (No root required) Within Games I have found no problems with the original Touchwiz.
Unfortunately, Samsung has once again "Bloatware" thrown in masses on the tablet, which is why there is a star deduction. You can remove these apps though with root and Titanium Backup, but really should not be necessary.
