Kudos to the Dopod's TI OMAP processor. Operating at 195MHz, despite clocking in at less than half the speed of the Xda Atom, the 818 Pro actually seems speedier, generally more responsive and with shorter loading times than the O2. With Windows Mobile 5.0, tapping the cross on the top right-hand of the program only closes the window with the program still running in the background. Thus, even though the 818 Pro comes with a generous 128MB of ROM and 64MB of RAM, users can still benefit from freeing up valuable resources allocated to open but seldom used programs by clearing them from memory via the Settings page.
