TP vs Diamond (owners of both)

[SRT 10]

I had a Mogul to a Touch to an 800w, now have an Instinct for a week....love the instinct form factor, however missing all the pda functions. Is the TP that much better than the Diamond. I undersand the differences, however I question the moving parts, slow screen rotation & added weight and thickness. Overall for those of you that both...which one do u prefer....Id appreciate some help....I would like one of them, however Im just confused. Thanks
