The best combination yet... of a PDA and mobile phone. Bloomberg Boot Camp, a report on today's technology. Samsung and Kyocera have devices on the market already marrying cell phone technology with the Palm computer platform. The Visor Phone... has been available as an add-on for the Handspring Visor. But when it comes to packing features into a truly pocket-sized PDA... .Handspring's new Treo line is the new king of the hill. Shipping by the end of this year for under four hundred dollars, with a service contract... the Treo will come in two flavors to begin with, one with the usual handwriting recognition... and the other, with a thumb operated keyboard much like the rival Blackberry device. Handspring VP Joe Sipher...

"The original vision was really, that person who is carrying around multiple devices... they carry around a phone, they carry around an organizer, they carry around a paging device... and combining it all into one pocketable device. And we think we've really done it in an elegant way."

The 5.4 ounce Treo uses the GSM network... .but a key feature is, it will be upgradeable to the next generation of wireless technology as it is rolled out. And the integration of the phone and PDA is as intuitive as it can be...

"I can look up any name in about three taps. And then I can press a button and dial."

If you are thinking of buying, keep in mind a color version will be on the market by the middle of next year. You can find more information at handspring.com. Bloomberg Boot Camp, I'm Fred Fishkin.
