 Before the Pocket PC brand was launched, there were other Windows-based machines of the same form factor made by HP, Philips, and others called Palm-size PCs.These devices ran Windows CE 2.0–2.11 and had an interface that was similar to the then-current desktop versions of Windows, such as Windows 98.Pocket PCs were manufactured and sold by several different companies; the major manufacturers include HP (under the iPAQ and now defunct Jornada brands), Toshiba, Acer, Asus, Dell (under the now defunct Axim brand), Fujitsu Siemens, E-TEN, HTC, and ViewSonic.
