WiFi or Wireless WAN?
Kevin C. Tofel over at jkOnTheRun poses a very interesting question: Would you give up integrated WiFi for WWAN? Some UMPC devices only have one mini-PCI slot, and could accommodate either a WLAN or WWAN module. Or its possible that one may want on or the other, to keep weight in the computer down, and eliminate one power drain - WiFi is terribly power-hungry.
With 3G services like EVDO and/or HSDPA, you have a nearly equivalent Internet connection speed as a WiFi connection (remember its the cable/DSL connection speed that may limit your Internet at a Hotspot). The only downside would be associated computers at your office or residence, but if you are talking only about a Ultra Mobile PC - it may be an Internet-only device anyway.
Thoughts?
