I while back I asked about upgrading from Windows 7 to Windows 8 on a desktop system; times gone by and folk have had more time to get used to the new setup.
Generally the new Metro interface (and I like Aero with its thumbnail previews from the taskbar) seems to be a bit of a pain in a non-touch desktop environment and the lack of a proper task bar/Start Menu seems a nuisance too. Having said that, some people seem to really rate Windows 8 and a number of magazine/online reviews I've seen seem to suggest that Windows 8 is more efficient and less resource hungry than Windows 7; £40 for an upgrade to Windows 8 Pro isn't bad either.
Can Metro not be installed (or uninstalled) as a feature of Windows or will it always be there necessitating clicking through to the desktop and can you reinstate the Start Menu?
Generally then, is it worth upgrading to Windows 8 from a stable Windows 7 installation in a non-touch, desktop environment?
