Pleasant. That doesn't sound like much of an accomplishment, or a benchmark or like, impressive. But the truth is, most technology isn't pleasant. The new Windows Phone is. Very much so.
It feels alive. Everything bounces. Everything swoops. Everything flips. Every single action is lushly animated. It just doesn't sweat the details—blood was spilled. The lock screen isn't a simple shade. It has a sense of weight and gravity; the further up you drag it before you let go, the faster it slams back down (if you don't completely unlock it). It's almost like the phone is happy to be alive. Which kind of makes you feel happy to use it. No other phone is like that.
Windows Phone 7, when it launched back in October, was like a very promising baby. It was cute and reasonably genius-y for its age, but it also frequently shit the bed and was missing some teeth. By which I mean, in this painfully extended metaphor, it was missing major things like multitasking and copy & paste, piled on top of a load of other tiny deficiencies. It's grown up quick. Now, it feels like a complete person.
