Can I still upgrade from Vista to Windows 10 or should I buy a new PC?

Vista users need to estimate how long their PC will remain usable before they decide to upgrade, but a few loopholes exist

I currently have Windows Vista. Can I upgrade to Windows 10? If buying a new machine, for normal personal use for email and internet, what would you recommend? Laptop and desktop options would be useful. E&AB

Sadly, you can't upgrade directly from Windows Vista to Windows 10: Microsoft only supports upgrades from Windows 7, Windows 8 and Windows 8.1. Vista was the current version of Windows from January 2007 until July 2009, so any surviving Vista PCs are presumably more than seven years old. If they are laptops, they are probably due for replacement. Even if they are desktops, they may not be worth the upgrade cost.
