The Microsoft has gone through a great deal of preliminary inquiry to get to know what the ideal balance of ergonomics is. The conclusion looked exactly like a 3.5″ QVGA (320×240) display, which found a wide implementation in many of their PDAs based off the Windows Mobile software platform. Over the course of time pureblood PDAs got to lose their market importance. This situation means that most manufacturers switched their priorities to PDA phones.

One of the most important development tasks was to minimize the device dimensions. The first module to suffer was the screen. It squeezed from the usual PDA dimensions down to 2.8″ or sometimes even 2.6″ or 2.4″. Some of the manufacturers were quick enough to make a real hype out of their VGA-standard matrices, which let the PDA screens become smaller.

The HTC does not seem to be proud of their marketing achievements at all (unlike others, e.g. E-TEN) which mean little to nothing when there are more close-to-life and way more serious issues to solve. Without setting up much ado, the HTC has developed their brand new customization system to sort out some of the hackneyed Windows Mobile OS issues, following the trend started by Samsung (just think of the latest F700).

Nowadays, HTC presents their new Touch Dual device (also known as Nike). The new device sports many software improvements. However, the HTC is mainly focused on the old and well-known goal - minimizing the use of stylus to the limit in frequently used applications, quite a contrary to what E-TEN and the rest of VGA-preachers are trying to shape as the world PDA phone design standard.

HTC Touch Dual is powered by ARM11 CPU running at 400 Mhz – the same as that found in the HTC TyTN II. The RAM volume has been improved upon the original Touch – now the device comes with 128 Mb onboard. The communicator supports microSD cards (SD 2.0 and SDHC as well).
