Linux vs WinCE in my case

Hi all,

Still searching for answers on the web before we start off with this 'new
terminal' thingy.
I can keep it simple saying the specs for that terminal are like a bus
system, PC104 would be close enough.
We are a 20 employee company specialised in data-communication for
transport-industries. All of wich are service,finance,project,sales and
ofcourse R&D-employees.
We want to use make software:
1. Stable
2. Driver-support
3. Short time to market
4. Nice user interface.

Out of three software-developpers 1 is used to design/build server-side
Delphi-apps for Windows.
Another is used to design/build embedded C for the old 8-bit client. The
third only builds.

So now my question: LINUX or WINDOWS CE?

Please some help would be nice.
