It's like, when toasters first came out, everyone had to have one, and growth was steep. But now, everyone already has a toaster, and we only replace them when they stop working.
But in this market, even replacements can often be hard to find. I have a 10 inch Dell laptop running Xubuntu that I use to work on hobby coding projects while riding public transit to and from my day job. But since December 2012, it's hard to find a 10 inch laptop. With what should I replace it once it stops working? I looked around, and unfortunately, the 10 inch 2-in-1s such as ASUS Transformer Book don't seem to work well with any X11/Linux distribution that I'm aware of.
