I have written about my happiness with my Treo 600. This device has been so successful in the marketplace that it has helped PalmOne's stock rocket from around $10 at the beginning of the year to about $35 a share today.

The only thing the Treo is missing is fast connectivity to the Internet (for both email and Web browsing). The Palm folks really need to add Wi-Fi to make the Treo go from red-hot to white-hot.

In the meantime, HP is jumping into the battle with its new IPAQ 6315. I have not seen this device, but it will have a QWERTY keyboard and connectivity for phone calls (GSM) and Wi-Fi. The 6315 sounds like the perfect device to take on the Treo 600 and also to compete with the latest versions of RIM's Blackberry.

I cannot wait to try the HP 6315. I have been a firm believer that millions of people will one day prefer to have one device rather than carrying around a PDA and a cell phone. And I believe that the winning device will incorporate a QWERTY keyboard. Obviously there are many phone-like devices in the market that connect to the Net, but few have a QWERTY keyboard. RIM and PalmOne have the lead, but the 6315 just might catch fire on its release.
