I am currently using it as a portable "laptop" mode with a portable monitor plugged into Sabrent Dock and with a wireless mechanical keyboard and mouse. I am using the included ASUS adapter, but it shows me this message "does not support full performance".
I hope they fix the issue. I read that they are aware of it.
Update took about 2 hours... System Updates, BIOS updates, Window Updates, Drive Updates.
Also, when updating BIOS, remove Ally from any dock, just plug in original adapter and restart, it will go into BIOS update mode automatically. I was using the dock and the Ally will only shutdown when trying to update BIOS
EDIT : Also, it works great as a laptop replacement! Very smooth performance, web browsing, etc.
