It is not a dislike its the fact that the bugs pop up at the worst possible times. If I am doing a presentation my laptop is always handy and it always works (mac). Email is flaky on the Treo and works when it wants to, since email and talking on my phone is my priority I use the Blackberry. Word and Excel also work fine on the BB.

Comparing a Treo to a laptop is like comparing a Ferrari to a go-cart.

If you have plenty of time to spare fartin around with your phone to keep it running run with the Treo but if you want battery life and reliability get the BB. I used to like the Treo but once I was convinced to use BB I never looked back.

(Disclaimer)
Like any other techie that can change tomorrow. I do like the new Nokia PDA phone.
