Hardware, Embedded Systems One Laptop Per Child is planning to end the production of its XO-1 laptop as well as drop AMD's x86 Geode processor. OLPC intends to replace these with a low-powered ARM alternative in the XO-2 laptop, which is slated for release in about 18 months. Even though the current XO-1 model consumes a mere five watts, OLPC feels thats the biggest problem. "We're seeing some very impressive system-on-chip designs that provide both fundamentally low-power demands and the kind of fine-grained power management ... in the XO-1," said Ed McNierney, chief technology officer at OLPC. Though using ARM architecture will reduce power consumption, it puts using the full-fledged Windows OS on their laptops in jeopardy. The company is currently wrestling Microsoft in order to try to get them to develop a full version of Windows to be able to run on ARM processors. It's not likely Microsoft will budge on the subject as ingrained as x86 is and how seemingly little there is in it for them, but we've been surprised before.

A large portion of .NET applications use P/Invokes to access processor-specific native Windows DLLs. This pretty much kills the prospect of cross-CPU compatibility.

It might be possible to develop managed applications with Mono, since the runtime exists for other CPU architectures--including ARM?

But how many popular commercial .NET applications are 100% managed (no access to unmanaged libraries) and target or even support the Mono runtime?

yes that's why it's a hell to try to install .net v1 on nt4 and, difficult to install .net v3.5 on windows 2000(sic).
I also think that people need to target alternate runtime ( Mono or even dotGNU ). But lastest feature always look nice in the eyes of a developper.
Maybe we should stick to java ;) .
