For connectivity, you get the usual bundle of PsiWin 2.3. As with all other PDA's from Psion, the 640x240, 256 color screen is touch sensitive. The spec sheet says memory is expandable through an MMC card, which means an extra 64MB is maximum.
Psion says this new PDA was "specifically engineered to bridge the gap between heavy-duty, keyboard-equipped industrial computers and lightweight professional consumer devices". I can believe that. It complies with the standard IP67 which basically means it's both watertight (as opposed to waterproof) and dust-tight, as well as rugged enough to withstand a drop onto concrete from 1,5m.
