One of the most common questions I get about MID's isn't a technical one - it's simply "where can I get one?"  Here is at least a partial answer of where you can currently find Intel Atom processor-based MIDs.

It's a tricky question, and even people inside Intel have a tough time keep track especially with different devices only available in some geographies. It also includes some high level features, and where you can go to buy them.  If I missed anything, let me know!

I no sooner put this together and it looks like we will have to add a Compal/SFR MID to the list once formal details are announced.

I should also point out that if you're interested in other mobile devices, there is also a wealth of information in the Product Portal at UMPCPortal.
