The $1000 still sounds totally adequate for surfing, office use and some light gaming, as long as you invest $20-$50 in a bigger SSD (or have some patience when starting software). Machines like this are still sold, they're just smaller and cheaper now. Even the 2012 $500 PC is probably fine if you upgrade the RAM, and even without that upgrade is not much different from some of the mini-PCs sold today [3]
