To follow up on my previous post: it appears Sandisk produces (d?) a combo CF card with WiFi and 128 MB flash on board that is compatible with Windows CE 2.11 and upwards. They go for relatively modest amounts of pecuniae on eBay. I'll let you know if it works.

See? That's the advantage of having one of them big, old card slots; even Nokia's Cardphone (does anyone remember it?) works with the SIMPad.

On the other hand, the SIMPad definitely won't fit in my pocket.
