While the original X6 has 32GB, Nokia decided to offer a lower-end model and so the 16GB version was born.

The Beam (or Halo) is a mobile handset with a built in projector from Texas Instruments.

The K01 is the same as the TG02 but with a slide out QWERTY keyboard. 
It’s another large (4.1″) touch screen phone in their Windows Mobile line. It’s got all the same specs but is slightly thicker thanks to the keyboard. It’s also got an AMOLED touch screen where the TG02 has a TFT and can manage up to 32GB microSD expansion.
The TG01 didn’t find much success in the market but Toshiba is pressing on with their Windows Mobile large touch screen line of phones. There hasn’t been much of a change to the specs from the prior version and Toshiba seems to think they can still find some success with this particularly feature-rich, 3G capable, 4.1″ touch screen phone.
The Vivaz Pro is an upgraded version of the recently announced Vivaz.
The major difference is the Pro has a slide out QWERTY keyboard on top of all of the other features. While some might think that is breaks the styling of the phone, it adds a mere 2mm to the thickness and only 20 grams to its weight. Not a major price to pay for a full QWERTY keyboard.
