I used to have it on all the time but battery life was pants, so the last week I have switched it off until required, things such as connexted to my laptop as a modem and surfing this site to and from work etc, HSDPA rocks for speed but I can live with GPRS for polling gmail and the odd quick lookup on the web for train times and such like.
The other thing I now do is ue my WiFi again on my device when at home as quicker to switch on than 3G for similar speed
