Most of the preinstalled should be there still after the reset as they get automatically installed again (i dont know which dont )
The others you have to download from where you had them before, eg. the markets.
You could loose data which was stored with the apps (eg Bookmarks, notes...).
Atm there it is not possible to do a full backup of the tablet (without rooting).
Lenovo did not support us there.
