Windows 8 and TIKFAM
Windows 8 is a perfectly good OS, it boots faster and runs smoother than 7 on similar hardware and it runs anything Windows 7 did (almost). Sure there are glitches in updates, just look it iOS7, that's not new and it won't stop happening anytime soon. If you're a serious business user just hold off 6 months on major changes and it'll be fine. There is only a little over 6 years left on Windows 7's support lifecycle... I sell to plenty of business who think 6 years is a minimum hardware lifespan, not maximum.
TIKFAM is weird and takes some practice. Sure it makes more sense on a touch screen but it works well enough to launch a program. There are limited numbers of good apps in the store... so ignore it. If TIKFAM bothers you so much just install StartIsBack and never see TIKFAM again, really it works just like 7, you would barely notice.
PS: My laptop is affected by the mouse issues, the touchpad has stopped responding twice since I installed 8.1, but it reboots in under 20 seconds... really it wasn't the end of the world.
