XP is not Windows 8. Do not try to make it sound the same.
XP was extremely popular and caught on fast unlike Windows 8 after over a year and a half is barely catching on. Yes I remember there were the Windows 98 die hards and some businesses who prefered to lose more money being hacked and downtime sticking with Windows 98SE than to use XP because the cost accountants didn't want to pay for software upgrades.
However today 90% of all corporations are refusing to leave XP behind until last year or two unlike XP. The companies that held onto Windows 98 for life in 2004 were in the tiny 15% range. Not the 90% who are kicking and screaming leaving Windows 7.
Where I work we are making people local admins and hacking and disabling security to make XP only apps run in Windows 7 rather than pay for an upgrade. But we waited until the last minute because XP was such an awesome OS and the best ever written according to the staff. If XP were supported for 10 more years they would keep running it until 2024.
Almost everyone loved XP. Yes I had Windows 2000 too back in the early XP era and used it for many years too. However it did not have universal plug and play nor a firewall. Want to do a .torrent? Manually do an exception UGH. IE was stuck at IE 6. DirectX stagnated etc.
