I work for a telus dealer in Alberta and I can say this: BB is better in terms of signal and features.
Palm does have it's advantages, such as native ms word, excel, and PDF support. The treo 755p(newest one) has built in google maps too and the battery life is great. And the touchscreen is cool.
However, my issues with include: complexity with settings and email accounts compared to BB; they are still huge and heavy; BB's have better signal - more dropped calls when comparing the two.
Hope this helps.
