Absolutely not. XP is not obsolete, not even with SP2. Vanilla or SP1, more than likely that would be a yes. SP2 added a big, important component, a firewall. Now, time for a bit of a rant about XP and MS. Microsoft is just telling you it is obsolete so that you have to shell out more money to buy a newer, inferior OS from them. Windows 2000 is my day to day main operating system and while a few things are getting harder to do with it, I wouldn't consider it obsolete. The only thing that makes it obsolete is all the random doodads that really don't mean anything. I won't get for the life of me how Microsoft Office cannot run on Windows XP anymore, what was truly added to it to make it not run anymore? My money is on nothing, that they just added just enough new extensions so that it calls upon dlls that do not exist in XP. It's exactly the same kernel, from NT to now, it's the same dang thing except up and sometimes downgraded, like the last OSs that came out. Windows 2000 and Windows XP are literally the same OS except for some enhancements to XP but many of the inner workings come straight from 2000 itself. But there was such a big compatibility difference between the two since somehow XP incorporated 9x workings as well so that many programs for 9x could also run without the error messages from being an NT OS which was a big problem in the 90s. But I'm elaborating too much. Honestly, I don't care what people say. It has aged a lot, yes. But it has aged gracefully. There is really no reason why Windows XP cannot be used for another 10 years. Security holes will always exist, there will never been an entirely iron clad OS, there will always be security updates and hotfixes. As XP becomes more incompatible, it'll probably take the same route as Windows 98 where many new worms and viruses will not run simply because it requires dlls that do not exist. There might be things that will always harm the OS, but worms generally attack what is being ran the most throughout the world. XP might still be a target now since many computers still run the OS, but so many have jumped ship to Windows 7, 8, and even 10, that attacking XP won't be economical for them to do anymore, which is what I believe Windows 98 is at right now. It just doesn't make sense to make backwards code for it simply because few people run it anymore, and if they do, some aren't even online with those machines. Many people on here will run XP until there's nothing in the world that will not run it anymore just because they are that diehard of a user. It's not because they're stubborn, it's because they prefer to stay on what works for them. As far as I'm concerned, NT6 is a resource hog and slows down quickly after a while if you do too many projects with the machine, especially video editing and the like. That's my two cents though. As for SP3, I don't think I'd necessarily jump to it. Most hardware that does support XP requires SP3 but if you don't need it, I don't think I'd necessarily install it unless you're having problems with security. I never really liked SP3 myself, it just felt a bit clunky.
