Handera (formerly TRG) has a new handhled that supports both SD and CompactFlash upgrades in the same unit -- two different ports.
It's a Palm III-based device, and Handera is a Palm licensee. They have other benefits to their handheld as well, such as a larger (albeit greyscale) screen. They already list it as compatible with several CF 10Base-T Ethernet solutions, although I'm not sure how they do it -- maybe they provide drivers?
Hopefully, this implies that they'll work with newer wireless cards (as well as any SD cards Palm gets out). Although I still can't see myself using a Palm for Web browsing and e-mail (hey, even my laptop sometimes feels cramped for that), I can see interesting uses for network and wireless access in the handheld itself. (If only I handn't saved up money for a Newton to buy it the month they canned it ...)
If they put a color screen in this unit, it would instantly jump to the top of the pack for me, in terms of purchasing a new Palm handheld. And I stick with Palm because they at least provide a bit of Mac OS support -- I don't expect that from Pocket PC (although that platform is gaining significance on my university's campus), except from third parties.
