Thanks for the quick reply. I'll ask the vendors if it comes with CF and
what version.
I can count on being connected. Right now it is a terminal emulation to a
Unix server using vt 220 emulation. We have used that for ages and have now
recently upgraded the devices and network. They now are all connected
wirelessly all the time. We went to a lot of effort to make sure there were
no dead spots (otherwise they lose their connection to the unix box and have
to log back in).

I have been reading up and I get confused on what is possible. Can I
count that both of the above have compact 2.0 framework?
No, you can't count on this, although they may have .NET CF 2.0.
Does CE.Net 4.2 come with compact framework or does that need to be
installed?
As with *all* components of Windows CE, this is *entirely* up to the
device OEM. There is absolutely nothing that you can say generally about
Compact Framework and Windows CE devices. Some have it, either .NET CF
1.0 or 2.0, you can't tell which, some will not have it at all.
These two devices are very similar (same screen resolution for example).
The vendors websites are pretty vague so I might need to contact them
with further questions but I don't know what to ask.
So, my questions are:
What needs to be in place/what should I check on that I could tell if
these two devices could run the same app.
If the devices have the same version of the .NET CF on them, then the
program should run in a relatively similar manner on them all.
Can I / should I call SQL Server directly from the device or would web
services be better/easier way to develop.
There's no right answer to this question. It's much more direct to
contact the server with no Web service in the middle and that's probably
how I'd do it on our devices, as they are generally fixed in space or in
areas where network connectivity is relatively reliable. However, if your
devices are totally mobile, you can't count on the network being there at
all 100% of the time. In that case, merge replication would be a better
choice (effectively eliminating Web services), as you can trigger
replication when you're sure that you're in range of the network or at the
end of a day or in some better situation that only you would recognize.
MR is *much* more-difficult to set up, so I wouldn't use it unless you
have to, but, if you are in an intermittent connection environment, it's
designed for your situation.
