From a fellow 4150 user. I agree it is a great device. I'm going to miss the small size and large screen when I eventually do upgrade to something newer.
Enjoy the forums here. I've learned a lot over the last several months, and there always seems to be a friendly soul out there to answer a question on anything PPC related.
P.S. My avatar is my daughter, Ella, who is also much prettier than my 4150.
