Performance is great, and Kodi works like a champ on it. In function I love everything about it.That said I had the power go out while it was updating drivers, and I lost wifi capabilities. After trying to restore and realizing that the restore partition was screwed up by the upgrade to wondows 10, I contacted Quantum's customer service email 3 times asking for a reinstall image, or at least a Windows key so I could an install image myself. They haven't responded once after several weeks. I got myself an image and reisntalled from a thumbstick and it's working again. But it's in eveluation mode for 30 days and the manufacturer won't get back to me with a key.On top of that, since all I use it for is Kodi and media playback, I figured "hey I'll install Ubuntu instead of Windows, Intel's stick runs Ubuntu so this should too". This bios is configured to not boot from a thumbstick unless it's a Windows imaged stick. I fought with it for 4 hours a couple weeks ago, trying to get it to boot Ubuntu. Press F7 on boot, and it sees the Ubuntu stick, but when selected it just restarts.I made a Windows 10 boot stick and started right up.Update (1/13/2016): Finally got the appropriate files from technical support and made backups in case anything like this happens again.
