I'm a computer technician, and i need to stay connected to my clients at all times. Ive tried smart phones such as the iphone 3g and the HTC touch pro, but they all lack some of the features i am looking for. I came upon the N810 about a month ago and i think it would fit in well, in my day to day life and would like to ask a few questions before i buy it:

1. can i use the bluetooth to connect it to my phone and make/receive calls and text messages?

2. Ive heard that the default web mail reader is crap. Is there an alternative or an improved version available?

3. In my line of work, i need quick access to the internet to google search computer problems at clients homes. How good would the n810 be for this kind of job?

4. finally, i need to read word documents sent to my email every once in a while, and pulling out my laptop is a hassle, is the n810 capable of opening .doc and .pdf?

Any help would be greatly appreciated.
