Anyone heard of "Gumstix"?
They make an embedded linux COM the size of a stick of gum, hence the name obviously.
What's cool is that, if you have a company, you can work with them to develop new COM's and such and prototype your product, something like that.
But what's really cool is that they have the electronic barebones to allow anyone to build their own custom cell phone or PDA, because they sell 3.5" and 4.3" LCD's, the expansion board to connect the LCD to make it touch screen, and the gumstix electronics board. Hook it all up and you've got yourself a mini-internet device.
Depending on the gumstix you buy, it can also have wifi and bluetooth, but they only carry wireless b and g models, no n as of yet.

EDIT: So the point is, wouldn't it be awesome to build your own PDA? Definitely going to do this sometime.
Although there are some limitations compared to smartphones; as previously stated no Wireless N, and the memory setup is a little bit different, it uses a micro SD card to store the OS, and I assume apps, on.
