I bought a new laptop (my first one!
) and it came with Windows 8.1.
Got used to it in 2 days.
In desktop mode, which I use 95% of the time, it is almost same as Windows 7.
But what I have noticed is that it is more buggier than Win 7.
First, I tried to remove my lockscreen PIN and the settings app always crashed while doing it. It worked only after many reboots.
Hot Corners (for bringing up Charms bar and Multitask bar with a mouse) randomly stops working even when it is set to ON and only a reboot solves it (only for a short while). Very frustrating.
I've seen a few more bugs like these and many glitchy animations in Win 8.1 even with the latest patch update.
I do like some things with Win 8 like the quick bootup (this doesn't work sometimes too) and also the ability to play tablet/phone games on my laptop (I have a pretty weak phone.
)
I miss Win 7 Aero though...
