- Socket's Wireless LAN Type 1 CF Card WL6000-320)
- Socket's SDIO Wireless LAN Card (WL6200-480)
- Sprint's PCS Vision CF2031 CDMA 1XRTT Type II CF Card (SPR-YCF2031CFC)
- Audivox's GSM/GPRS Type I CF Card (RTM8000D)
I haven't used the Audiovox card but have used GPRS for Internet access and found it much slower than advertised. I have used the CF2031 card and found it both slow and unwieldy (see this column).
That said, wireless WANs are a better choice if you need to access the Internet from just about anywhere. Wireless LANs require you to be within a hundred feet or so of a wireless access point or hotspot. Also consider how much you're willing to pay for Internet access. Wireless WANs require an account with a carrier and usually incur monthly fees; wireless LAN hotspots offer daily/hourly pay-as-you-go rates that might make more sense for occasional use.
