If you plan to start it, this is my vote for Vi. ;)

Which is about the same time & amount it would cost me to learn to use
the Windows operating system. You should have learned the right OS right
away...

This omits some further estimates:
Development machine OS (Some version of Windoze) = $500
Cost of down time when it crashes (yearly) = $2000
Cost of auxiliary anti-virus software = $70
Yearly cost of maintenance of above = $50
Risk of MS theft (allowed per EULA) = ???
not to mention that the MS support largely consists of "reboot. If
it doesn't work reload".

And try getting source for the suspected system from MS.

You can't afford Lunix for this.
If all you need is serial in and TCP/IP out what the hell do you need an
RTOS like Linux for? Whilst Linux is "free" for the SW (watch costs
for time to get it all working) I suspect that you could do your system
on a small micro with very little memory. It will cost you quite a lot
per unit for the HW to run Linux and the app.
I am sure there are some FREE TCP/IP stacks around (
see http://www.embeddedinternet.com ) so you won't need an RTOS as well.

If You need just to collect data from serial port and sent it over GPRS
You can do everything inside GSM module.
Almost all new modules supports scripting/high level languages (Python,
Java, even C++) and has built-in TCP/IP stack.
In my opinion it will be cheapest solution.
Look for wavecomm, telit or siemens GSM modules.
I think, even simple processing of data could be done inside GSM module.

I would be interested to know the driver for choosing Linux. Can you
provide more information on the application? So far we know you want to
receive serial data and write to a GPRS modem with the lowest cost
development system and run time cost - an 8051 would seem to fit the bill so
far ;-) but not with Linux or a PCI modem. naturally......
