Against moving off XP is the necessity of purchasing/buying new computing hardware, since older machines are not likely to run Windows 8 or 8.1 very well.
Then too, there is no direct upgrade path to 8 or 8.1 from XP as there is from XP to Vista. Not possible to upgrade from XP to Windows 7, a clean install of Windows 7 is required to get there. If XP to 7 does not work, then certainly upgrading XP to 8 won't work either.
Some find it irksome that Microsoft is pushing 8.1 instead of offering 7, there's that too.
Latest survey says XP still is in use, as of today, by 29.1% of known systems connected to the Internet. Not only are these users facing a problem, so is Microsoft, as well, if this number does not drop to 0% soon.
Running older XP systems can be done safely, but only if some version of Linux is installed and XP is tossed out the door by April 8th, 2014.
