Me contracts up on me Blackberry so it's time to ring up Virgin and demand succor.

Hopefully I can grind them into giving me a good tariff and a shiny new phone, so here is my question:

I quite like the keyboard on me Blackberry, I find it easy for doing texts and e-mails and search terms. Will I miss this on a touchscreen only gizmo? Do the benefits of a Samsung/HTC Android outweigh this compared to a non-touchscreen Blackberry?
