I think there are some simple reasons as to why a SD WiFi card might not run as fast as a PCI or PCMCIA WiFi card in a desktop or laptop computer.

As Gerry Blackwell pointed out, his testing used an FTP transfer. This is highly dependent on the host platform, host memory and storage. You might expect that a PDA is not going to have the same memory performance or storage performance as a desktop PC. And then there is the question of CPU peformance as well.

Another thought that comes to mind is how do you set TCP parameters on a PDA? I have several utilities on my desktop PC that adjust things like MTU and RCWIN which have a major impact on network performance in a Windows envinronment. Is there something similar under Pocket PC?

Gerry should have used one of the many sites that don't rely on FTP transfers. There are plenty of them, all you have to do is search for "Broadband Speed Tests" or something like that. I don't know that a PDA WiFi card will ever be as fast as a desktop or laptop PC, however, the results that we have at the moment are inconclusive, IMHO.
