Easy peasy upgrade for me. It went almost flawlessly. Had a few system freezes after the upgrade (with no previous history), but the actual upgrade went quick and error free, and the freezes stopped after that first hour (all I can speculate is that one of the quiet post install updates fixed whatever caused them).
Actual performance is every bit as good as Win 8.1.
I would say for those with small drives (I for example run on an SSD--which gives me great performance but only 112 GB or so), you're going to have to make a HARD decision about whether or not to use the Disk Cleanup utility (from the menus or just tell Cortana to find it). If you do use it and tell it to include System Files you can get a TON of space back. But.. you lose your rollback ability. For me it was worth losing that. For others? Who knows.
Also, I beg of you... record your Windows License Key OFF your computer somewhere in case the upgrade goes SO wrong you have to start 100% from scratch again (with your previous install CDs/DVDs).
