I've got the worldphone (8800 I think?). I like it. It's my first PDA style thing-a-ma-jiggy, but it works fine for me. I thought I would use the browser, but rarely do. mostly e-mail. I first bought the Pearl and returned it after 2 days. Everything was just way too small. I do like the looks of the new Bold. But I've got about 18 months left before I can upgrade again.
Oh-another reason I got rid of the Pearl - Vaja didn't make a case for it. Gotta have a Vaja case.
