now here, the 5way D-Pad is clearly shown. is this D-Pad some kind of virtual one? if its virtual one, be sure to watch the pad more than the screen as i pretty sure instead of scrolling around you'll spend more time activating the apps.
and what does the tear-off screen means? well Nokia mayn't be very successful with it, but had it been Apple, it'll make hell lot of cash even if it turns out to be "unsurprisingly" unusable.
