Netbooks were huge because, before that time, small portable computers of any kind were sold at a premium and still came with performance compromises. Netbooks achieved a low price by doubling down on the performance compromises at a time when performance was becoming less important — native desktop applications were taking a backseat to lightly interactive web content, and “web applications” hadn’t become so bloated as to need tons of browser power.
I picked up an HP Mini in 2008 or 2009 for around $200 to hold me over for a few weeks while my main computer went away for warranty service, and it grew into a really reliable second device/backup/travel/guest computer. It also came with my first SSD… a whole 16 GB, but storage was never the point for me.
Later, when my custom-built home server inexplicably died, I installed Slackware on the Mini and it had a nice second life until the Raspberry Pi — even less powerful but still good enough — came along.
