Compared to the iPhone, yes. But back then, before the iPhone, it *was* the PDA market leader and it was *THE* geek mobile OS - the Linux-based Sharp Zaurus was very rare outside Japan. Remember, back then there were no mobile devices with desktop OS'es - the OQO came out later. That is, if we wanted to have something REALLY powerful in our pocket for gaming (tons of console emulators etc.) / Internet (Web, mail etc.) / MP3 / video player / eBook reader / generic computing device, we chose WinCE / Pocket PC. Palm OS, Blackberry and Symbian were waaaay less "geeky" / powerful with WAY worse 3rd party SW support (video players, games etc).
