It's difficult to assert that an interface in its entirety is unrefined or unfinished having only used it for a few minutes. I very rarely found myself confused or frustrated by the interface after using it for a day. Every devices has its flaws, every user his/her preferences and expectations. I bought it because I wanted a fully open Linux OS running in my pocket. Not to be snarky (ok, maybe a little), but if I wanted a Fisher Price toy, I'd buy an Apple product. The two devices decisively appeal to different crowds.
