It drives me crazy that there are any number of companies providing cheap digital voice and text messaging services, but they can't do a simple TCP/IP link.
There's one problem I see. If I'm talking on my Cingular phone, and I drive out of Cingular's coverage area and into Cellular One's, they're smart enough to start routing my calls that way. However, if I were using an IP address owned by Cingular, is Windows smart enough to let Cellular One tell it I have a new IP address now?

WiFi runs a lot faster than GPRS. Eight slot GPRS will give you about 115.2 kbps, whereas WiFi gives you ~10 Mbps. Both are best case figures.

Email and web browsing don't need 10Mbps. I suppose you could pull MP3's (or vorbis) while wandering round town, but I would still get them at home where bandwidth is (and will be for some time yet) cheaper and carry them with me.
"3G promises increased bandwidth, up to 384 Kbps when a device is stationary or moving at pedestrian speed, 128 Kbps in a car, and 2 Mbps in fixed applications." (Webopedia)

EDGE [gsmworld.com] will offer about 3x the data rates of GPRS whilst still using similar technology. So, it would be around the 350 kbps mark in (very) good radio conditions. 3G technology (in the current delayed timeframe) is looking less revolutionary and more evolutionary all the time.
Re:GPRS (Score:2)
Of course, GPRS can cover several miles, whereas W-Fi's range is around 100m. There's always a trade-off.

GPRS are different (Score:2)
Nokia [nokia.com] sells a card [nokia.com] with support for both WiFi 802.11b and GPRS, maybe because the two things are different.
What you might see is automagic switch to 802.11b network when it's scanned to provide better and trustable bit-rate, and switch back to GPRS when the WLAN network fails.

The biggest technical problem from what I can see would be for IP addrs and routers.
It seems the system gets round this - essentially it's one network, and the IP follows the user around. From the article:
A single IP address can be used in multiple mobile networks, including those based on next-generation standards.
I assume this is handled by Green Packet's SONaccess IP routers [greenpacket.com]. The article is basically about (one of) the first use(s) of this system.

I'm definitely going to follow up on this Ipaq Linux stuff. As for the Zaurus, I was under the impression that it relied on a lot of Java.
A company I work with was considering using Linux on a line of Pocket PC type devices, but they thought they needed to use a lot of Java and that the licensing costs for Java were actually expensive compared to going with MS when they added in all the in-house development they had to do.
But I must admit I didn't know about iPaq Linux. If it's less dependent on Java it might be quite interesting.

The current generation is built on StrongArm206 CPUs and the Xscale 400MHz CPUs are coming already in production so bloated software isn't really as big of an issue as it is on say a cell phone.
I think this IPaQ stuff looks very intriguing, but I'm afraid my suspicions are confirmed on further research. They've got TWM up with a few basic apps that need major tweaking just to view properly. This is a far cry from KDE or Gnome with OpenOffice Lite and Navigator for PocketLinux.
I'm not complaining. I'm just surprised nobody is more aggressive in this market as it looks like the volume is definitely heading north on these puppies and the dealing would be done as a wholesale licensing rather than retail so it should be profitable. The big question mark is, how much is Windows really charging for licenses? Who knows?

I was making the mistake of thinking is was Ximian so I was sort of dismissing it out of hand as I was just at the Ximian site a few weeks ago and there was nothing about wireless. But Symbian, hey, they've got it goin' on. And the MS troll above should take a look as well.
