Unlike previous cellular-wireless iPAQs, the 510 has a numberpad, not a buit-in keyboard. It also doesn’t have a touchscreen. However, its QVGA screen has a higher resolution that other cellular-wireless devices from this company, like the iPAQ hw6900 series. The 510 runs Windows Mobile 6 Standard on a 200 MHz TI OMAP processor. This smartphone includes 64 MB of RAM and 128 MB of ROM.
