"In my case I installed a FREE one-meg utility (much smaller than either my anti-virus, my anti-spyware or my registry cleaner)"
The thought of having to endure Windows 8 made me switch to Linux Mint Cinnamon edition (after road testing a couple of other desktops along the way)... By default I have a start button and don't need anti-virus, anti-spyware or a registry cleaner.
Apart from Metro, horizontal scrolling (ugh!), no start menu, signing in to MS accounts, apps not quitting from the X button, schizophrenic menu options depending whether you right or left click, hidden options/menus/hot corners, ugly flat window decoration, constantly being unexpectedly dumped between desktop and Metro... I'm sure Win 8 is lovely.
Thank you Microsoft for finally producing an OS so atrocious that it gave me the impetus to do something I'd been meaning to try for years. I feel at home again with my PC, like I've got all the best bits of usability from XP and 7 with the security, stability and customisation of Linux. The future's bright, the future's Minty.
