VIA Nano competes _directly_ rather with AMD Geode and Intel Atom; not (or far less) with ARM. It has some very nice advantages compared to the latter. For example, it has a hardware cryptography accelerator. Idle it uses 100mW. The TDP is rather high, but I bet they'll be underclocked by default. Its AMD64 compatible, with x86-32 mode available. So provides good backwards compatibility. I don't think this device is meant for (heavy) travelling like a phone, DAP, or n8x0 is. Its not compact enough, and the battery life would not be good enough either. So it competes rather with netbooks whereas the new tablet from Nokia will be aimed at travelling (long battery life, small, efficient, HSDPA). However, these markets will overlap more and more, with differences being less and less. And there is not room for many players and many architectures in this segment either.
