Yes, and we've known for several years that a specific date would come that Microsoft would stop supporting this operating system with patches. that date has now passed.
While I can understand such a point, I think in this case it's not consumerism that's driving the march ahead. It has been well know for a long time now that there are inherent limitations and flaws in the Windows XP architecture. For several years now, the resolution to those flaws has been to use a newer operating system that has those issues mitigated.
You're right that "old" doesn't necessarily mean "bad." But in Windows XP's case, it was "bad" long before it was "old." And there is a limit to how long a vendor can reasonably continue to patch holes in a bad architecture. We're past that limit now. It's time to move on.
I would chalk that up to Microsoft doing a very poor job of offering and promoting better alternatives, and because users are fearful of switching to different, more modern platforms... NOT because XP is such a good architecture given the current computing climate.
Welp, I can tell you with certainty that you will see more issues crop up over time. Bellyaching over why you should be allowed to continue to use such a "good" OS well pat its prime, is only going to fall on deaf ears. The decision has been made by Microsoft. You can acknowledge that now, or have a really hard time of it later. The choice is entirely yours.
So by your estimation should I absolutely not have this computer connected to the internet? It is a Dell from 2005, it was top of the line when I bought and still runs perfectly fine for my needs. It's by no means fast but I never use my desktop anymore, only to download/sync/backup and for school/printing so I haven't upgraded. I browse almost exclusively on my iPhone. In fact, my next computer purchase will be a MacBook.
