Let's put this in perspective. Windows 7 was released four years ago, Windows XP was released 12 years ago. Depending on which version you got, the cost was $100 - $220.
Assuming you used XP every single day for four years, that works out to a daily cost of $0.13. Don't know about you, but I spend more than that on coffee every day.
Now that the cheapskate argument has been addressed, let's remember that an insecure computer doesn't just affect the owner, it affects everyone else on the net if it becomes part of a botnet.
I can understand old dogs not wanting to learn new tricks, but am surprised people who should know better (i.e. participants in a tech forum) advocating for the retention of XP.
Well one, I'm not advocating retention of XP, and two, the reason you don't get it is because you are looking at it strictly from a "i'm technical and why wouldn't you?" standpoint.
Since you went on the cost path, I will point out that you've completely left out the hardware considerations. Something I am surprised to see by a person on a tech forum. This is not a small part when there is hardware out there that simply isn't supported in newer versions. Yes yes, I know, we're technical, why would you use anything that is old, blah blah. That is not at all the point when you are talking about businesses and grandmas.
If you aren't using 64-bit, what exactly does 7 or 8 offer that can't be put into XP? Are people that are using 32-bit Win 7 less secure? Sure there are newer versions of protocols, but all of that can be put into XP.
I know people are going to sit here and argue that they are indeed more secure, but the reality is, they are just full of holes waiting to be found. Those are fixes that can be pushed out that DO NOT require a completely new OS jump.
The # of things that require that kind of jump are few and far between.
Most of the "7 and 8 are more secure than XP" comments are simply because of holes that have been patched. Holes that can be also be patched into XP if MS actually wanted to. Anyone who has worked with MS (and yes, I have directly worked with MS on these things) knows how difficult it can be to get them to address security issues.
Of course I know this discussion is a lost cause just by the couple of responses already, but just to clarify, I am an advocate of Windows 7, not so much 8. However, my reasons are for functionality and stability, not security. Obviously we should all patch security holes....but as usual I have to spell that out because people can't seem to read between the lines around here.
Let's put it this way. Talking about businesses and grandmas are almost identical. They both go with the "if it's not broke don't fix it" stand. In many cases, it's not just pay for an upgrade. There's way more involved than that and usually breaks something else that used to work just fine.
The only REAL reason for newer OS upgrades is for the features. ALA Gaming.
