What I liked least:
The Micro SD slot is limited to 32GB and the USB port (with supplied adapter)
no need to connect a key to more than 32 GB, still less an external hard drive.
All the videos files can not be read
There are a lot of software installed by Samsung that we can not uninstall, such as games
To sum up it is a good ideal tablet for basic internet use,
with some nice applications,
It will not replace a good computer but it really is a genius and interesting device.
I recommend it.
