First of all, this kind of statistic is pure bullsh1t to bring like this, even if 50% of ppl had HDD and not SSD, how many of them actually game? because SSD is like big priority if you are gaming and if its your hobby, you invest into it something, but if you use your PC for FB or once a day, ofc you wont invest in SSD, since its still quite expensive. Its like giving statistics here that half of the ppl are still using windows XP, just because millions of PCs in offices have those and companies cannot/dont want to switch to higher tier windows, but you wont find big amount of people who are gaming and using win XP
about sleep animation, yeah, probably something could be done about it, but i dont think its high priority as it is now? there are WAY more important things to take care of right now (and dont come and say "blah blah its 2 min job to delete it", maybe it is, maybe its not, you never know what kind of problems deleting some part of code makes)
