Hi, Gerard.

No, it is not the same amount of data. Terminal Services is sending deltas of the screen to the client, no data at all is going trough except this image. Even so, in a good designed Web application you tipically don't send the 200 customer records, but a smaller set based on some kind of filtering or paging mechanism.

Also, I'm assuming that you're talking about a Pocket PC device, where the Terminal Service client is not the most efficient one, and GPRS does not usually provide the best response time. A web app, on the other hand, could be quite prompt.

>>...the application will surely be easier to use. I don't think you'll have a very good user experience with Terminal Services over GPRS...
>As the app runs on the server , should'nt the experience be essentially the same, except in Terminal Services it is easier to prgram it as you are essentially programming a desktop app

Again, assuming a PPC app, you'll have to design special forms to adjust to the small screen, and what looks good and is usable in a typical desktop application don't necesarilly is the same for a stylus-based application.

If the use-cases are as simple as you told in the previous mail, I guess a web application coudl be really simple to put up; chaper and simpler to deploy also. But of course it all depends on your experience and existing infrastructure.

Best luck,
