I see BlackBerry taking Nextel's line and focusing on business. They are not doing well in the consumer market now that everyone has push email.
Microsoft will buy Palm and continue to make an OK phone OS but fail miserably with equipment.
Android will integrate into more and more things. It will replace Chrome as Google's OS of choice for anything not PC. Netbooks, indash units, possibly even DVR's.
Apple will continue to be the Bose of cellular. It will release things with lots of shine and even more hype that don't really innovate but they do intrigue.
RIM and Nextel arn't competitors. Two completly different industies. Heck, you can get BB phones on Nextel. Sprint will kill off IDEN (Nextel) when they are completly overlaid with WiMax. The last PTT dinosaurs will have to suffice with Qchat. This could be the perfect time for someone like Motorola to go back to something they know best, radio communications, purchase the block D 700mhz spectrum, and build a nationwide two way radio network for public service and buisness kinda like the TETRA network in Europe.
MS won't buy Palm. They should have before they made WM7. And I disagree about WM. Hardware has almost allways been it's strength. Anything we see on a phone today (camera, bluetooth, wifi, apps) started out in WM. It's the OS that has always been the problem. And MS hasn't kept up with the trends, and now it's dead. WM7 will die a quiet death within 3 years.
And you summed up Apple to a T. Though they take good ideas that others have had and make them work simple and easy. That was always one of the problems with smartphones, too hard for the average person to use until the iPhone.
I see our phones becoming our computers. Look at Japan. Almost 100% phone penetration, but PC's are in less than 1/2 of homes now and falling. Requiring a PC/Mac for activation and syncing is one reason the iPhone is almost non existent in Japan. Apple really need to do away with requireing iTunes for the iPhone/iPad. Include MobileMe with iPhone service to the carriers. Bundle the cost either with the device or as a monthly charge, but keep it to a couple of dollars a month at most (since they don't do anything for free).
Completly agree about Android. Were gonna see it in almost everything. Yesterday there was an article on Engadget and Gizmodo about an Android powered TV. We may see Android in toasters in a couple of years if things keep going they way they are.
