Full spec 400 Mhz + extras at US$263 -- true value!
Member Review I was looking very hard at the Zire 72 and had already decided to buy. But then I saw the Mio 339. It's not just the camera, it's PocketPC. The thing that finally convinced me is the flash! Even many digicams out there don't have flash!

not as good as it seems
Talkback well.sounds good, ~70 Mhz of spectrum on a band that will travel further than most.however for "broadband" speeds you need a 20 MHz channel ideally, so there are only three of these available.it is harder to define where these signals go as the...

Processor benchmarks: Intel versus AMD
Talkback As with A64's the raw cpu MHz of a Barton CPU is not of its own an indicator of how well it performs. The Barton is well capable of running at 400 MHz FSB as all Bartons are. Your CPU speed is nearly the same but your mobo and RAM is now at 400 MHz.

Will it work as expected?
Talkback This appears to be the system investigated by Nokia in about 2001 to use the GSM 900 MHz and 1800 MHz bands for a form of 3G style communications. They found it worked - but at the expense of the 'traditional' GSM signal, which was severely degraded.
