Update Dell today made official the details of its latest PDA line, the Axim X3, as revealed last month by the Federal Communications Commission (FCC) web site.

The X3 is offered in three versions: one, the X3i, with integrated 802.11b wireless networking, and two without.

All three models are based on Intel's XScale PDA255 processor. The X3i and the top-end X3 are clocked at 400MHz, the lower-end X3 at 300MHz. Every model features a 3.5in 240 x 320 16-bit colour transflective LCD, infrared connectivity and pack in a removable 950mAh Lithium Ion battery. They also offer an SD card slot, which Dell confirmed does indeed support I/O cards.

The 400MHz models ship with 64MB of SDRAM and 64MB of Flash ROM (16MB more than the FCC document specified), while the 300MHz version ships with 32MB of SDRAM and 32MB Flash.

The X3 range runs Windows Mobile 2003 for Pocket PCs.

The X3i weighs 140.4g (5oz), which the other two models come in at 136.5g (4.8oz), 28 per cent lighter than the old Axim X5. The X3 is 17 per cent thinner than the X5, Dell added. The X3i measures 12.2 x 7.7 x 1.5cm (4.8 x 3 x 0.6in). The non-wireless, antenna module-free versions are a few centimetres shorter.

In the US, the X3i costs $379, the 400MHz X3 $329 and the 300MHz version $229. UK prices are £269, £222 and £163 including sales tax, respectively. ®
