It's always nice to have an alternative, isn't it?

It will, of course, largely depend on the hardware the thing runs on (battery life especially, but also size and weight). But it could be tempting because it's more the desktop-like full-power experience that I look for in mobile devices, while Maemo seems to aim more for the phone-like, casual use cases (in terms of marketing and UI, not in terms of what the OS is capable of).
