True... I'm reinstalling my brothers laptop from 2010 right now. The disk was developing bad sectors, and we dumped a 500GB SSD in it. That's going to keep it rolling for another few years. It's got a quad core Sandy Bridge i7, 16GB RAM and now an SSD... Batteries can still be had for the laptop, so even that is covered.
I personally started just buying second hand machines. Lenovo X220? 159€ for a nice base configuration... Add in a small SSD and 16GB RAM and you have a really nifty portable machine for less than 400€. There simply is nothing that beats that kind of price/performance in the "new" market.
I've been saying for year we're at the "good enough" level... now, it's not only that, it's that several year old machines are "good enough".
Yes, I know, some of you do huge simulations, tons of virtualization, etc.... I'm talking for normal users, not you guys...
