For several weeks there have been rumors about Palm being bought out by either private equity firms, Motorola, or Nokia. Personally, I think it will be Motorola. It just makes sense. They already acquired Good Technology and Good's software is mostly used on Treo devices. The play here is for a larger market share of the business PDA market, which Motorola has never been successful at conquering. The release of the Moto Q was its first step, and Good's support for the product made it more palatable for corporations already using Good's software on other devices. Adding the Treo line (and probably discontinuing or selling off the other product lines) will give Motorola instant access to the corporate market. And Palm has been the only real competitor to the BlackBerry products. So we'll see in the next few days who will be Palm's new owner.
It is interesting that the Palm's first product, the Palm Pilot, was designed to do a few things very well - calendar, contacts, and tasks. That was over 10 years ago. Now the most essential functions are e-mail and phone, with contacts, calendar, and tasks still important - although in today's world they are all encompassed in "email" instead of being seen as three separate applications. No longer are those good enough on their own. And that's what the Treo does best - integrate all these "simple" functions into one device.
