Prada's phone is as close to the iPhone as you'll get. Everything is done with a tap of your finger. There are essentially no buttons to work with.
Once you get beyond how this looks, though, you'll face up to a major cell phone decision: do you really--I mean REALLY--like this feature? In my case, it's starting to feel like a "no." There's something to the tactile feel of a standard cell. Even with a flat panel (think Razr), you still get a feel for the numbers you're dialing. Not so here. You need to double-check everything. Odds are you've made at least one mistake. And getting to a keyboard after you've dialed (to punch in your voice mail password, for instance) is a task. Finally, you do need the side lock. But having to click it every 5 to 10 seconds gets tiresome.
Makes you wonder if the touch screen really will totally overtake sliders, clamshells, and candy bars.
