How do you access your email when away from your workstation?

I am looking at the Compaq iPAQ H3870 (http://www.compaq.com/products/handhelds/pocketpc/H3870.html) because it uses Bluetooth technology. I'm new to the whole 'mobile internet' thingy so i start getting confused when looking into what is actually needed for it to actually work!

If i were to get a Bluetooth compatible mobile (i'm looking at the Ericsson T68 (http://www2.sonyericssonmobile.com/T68/)), is that all i'd need? Or do i need any addons for the iPAQ?

With these two pieces of hardware i would be able to use HSCSD, which is up to 43kbps, network dependant. I'm in the UK and as far as i know only the Orange network currently supports this.

Or would it be better to get a laptop!? I do like the idea of having it all fit in your pocket though :D

I would also like to use this setup abroad, is it just a case of having 'roaming' activated from the phone network operator?

Thanks for any help.

can i run putty or any other ssh client on a ipaq?

I looked at that thread but it didn't answer my questions.
