They're perfect for 90% of users, who check email, update facebook/twitter/google+ and browse the web and do a bit of online shopping.
They even extend to music and video watching...
With the exception of video any half decent phone does all that and will also fit in your pocket. And I don't see what shopping is so urgent it can't be done on the PC at home.
The pen thing saves me a bundle of time but for general use I wouldn't recommend one to anyone.
