A lot of people still need to do their accounts. Every cheap, good system runs on Windows. "cloud-based" systems mean Internet access, not always available. For this purpose the netbook was perfect. We still keep an MSI Wind as backup in case a main computer fails, and its performance on email, basic spreadsheets and accounting programs is perfectly adequate. It also runs all day on the big battery and cost under £300 in total.
One of my wife's clients decided the other day he needed a new computer to do his book-keeping. He phoned up the local computer "specialist" and has ended up with £2500 spent on Windows 8.
Problem in a nutshell. Netbooks were too good; they cannibalised laptops. So the industry decided collectively to sell expensive ultrabooks, and tablets that are not actually good enough for any daily work. Problem solved.
