Blackberry vs Window Mobile

My new job will require me to do moderate-to-heavy travelling around the country and throughout Asia. Hence, it would be great to be able to keep up with my email at all time without the hassle of turning on my laptop. All I need is phone with push email that I believe will increase my efficiency and save me time.

So which one should I get a Blackberry (BB) or Window Mobile (WM) phone. In addition to this, is the 3G service is up to the standard in Malaysia, considering the limited coverage area and expensive rate-but the telco are expanding aggresively right now.

Here are some direct comparison of BB vs WM :

I tend to go for a BB , but having a WM would edge on (full access) to docs and spreadsheets. And hopefully (soon) I will able to make my decision of which one should I get then it would be a question of which telco should I subscribe too then of course the phone.
