In principle, a nice notebook with good price-performance ratio.
But the pre-installed Windows 8.0 bugs and the update to the Windows 8.1 does not work bearable.
You wait an eternity during the upgrade process, then there is eventually an error message and the old Windows 8.0 system is reactivated.
The problem is well known and in various Internet forums (incl. The Acer User Forum) discussed. There are no fundamental solution. Acer directly there to date nothing: an outrage actually!
So I can currently only advise the unit to buy. I'll probably send it back again. Too bad. But there are also other manufacturers offering devices with very similar features.
