Hi James. I left BlackBerry on a Bold, which I keep it just to look at and feel. It's gorgeous! I went Samsung for the bigger screens, but when the Keyone came out I spent 6 agonising months on here, and trying it out in CPW in Poole till I finally pulled the trigger . Got it through Clove UK as they're the only company I could find that could sell a black version to my company in Spain.
So, very happy to be on a PKB again and it feels enough like a real BB to keep me happy. I posted a fairly in depth non geek review here under the title an Honest John review of the Keyone, which might seal the deal for you. To be honest, if you're a BB fan, you're gonna enjoy this phone with any foibles you may find. Let us know what you decide. All the best
