I think it's an amazing system, after Windows 98, my family skipped 2000 and went straight to XP and never regretted it. I got the XP Media Center edition for myself and loved it, in fact i'm still using it right now(I downloaded the critical updates today, and my antivirus software is up to date, so i'm not worried about anything bad happening to my PC)
It's not hard to see why Micosoft kept it going for so long, it's easy to use and navigate, and many others seem to agree, as it's used for many ATM machines.
Microsoft has done plenty of things right, but I don't know if this is one of them. I'm definitely not going to get Windows 8 anytime soon, i've heard almost nothing but bad things about it.
I plan on keeping XP until at least i've finished all the older PC games I want to play that don't work on Windows 7.
Good riddance. Though, because the Netherlands is actually paying Microsoft for private patches, it isn't really going away. I'll be surprised if it ever will, considering a third of the Internet still uses it.
Or those savy enough to realize there was more than one version of XP. XP Home edition blows, which I can only assume that's what you tried.
XP Professional works great. It provides the equivalent experience as Windows 2000 from a developer's perspective. I've had no problems with it and have been running my laptop on it for the last 8 years or so. It's about time I replace it, but I've had no problems with it.
I figure I'll get a new Windows 8 machine and dump Linux on to my laptop to keep it functioning.
I used XP Professional on a now-deceased 2004(?) Dell Inspiron. It finally behaved well after removing that McAfee which the previous internet service from long ago managed to install. Minus the dying hard drive it held up pretty well.
My parents had the home edition of XP, it was pretty good, though i'm happy to have the 2005 Media Center edition.
Windows 8 is now getting the same bad reputation that Vista did when it came out, I have a feeling 7 will have it's lifespan extended as a result.
