I am not saying don't try other things, I am just saying that if someone is not familiar with Linux there are much simpler things than installing a new OS when the one that is on actually works perfectly well. There is little point in programs like k9copy, dvdrip etc when there's no CD or DVD on the machine.
Also, one of the real beauties of Linpus is it takes fifteen seconds to boot. These little devices are not fully fledged laptops, they are little devices for having when you're out and about or can't carry too much weight.
How fast to boot is this one you have tried, btw and how fast does it run in general compared to Linpus? (Genuine question, not being sarcastic.)
Also, it's all very well saying you have wired networking, but I'm willing to bet most people want wireless!
Saying that we'd all be stuck with Windows if we tried nothing new is all very well, but getting a newb to try something like changing an OS could well scare them away from Linux.
