I had this amazing smartphone for a fortnight.
In that time, I loved some things about it (its 4.3 inch screen, its slim design, its speed and its Sense user-interface). I was less enthused about one or two features, mainly that its operating system still lacks the fluency of iPhone and Android. It's available from €50 on an O2 billpay contract.
(Please forgive the modest quality of the videocamera: we await restitution of our proper HDV-cam.)
