I actually wasn't sure that I would like it after several years of Windows Mobile - but I did!
I returned it just inside the 7 day "cooling-off" period just in case and now I can't make up my mind whether to go for the Desire or wait and see if/when Orange get the Desire HD in.
I have heard rumours of them getting it sometime in October - it would be really nice to know a little bit more accurately though.
