HI all

New to the board and so far have been impressed with the wealth of information contained here. I'm looking for a pda that will allow me to login to my servers. I've seen the HP Ipaqs and the dell axims do the trick. In areas where there is no wireless available i'd have to use a phone to access the internet. Quetions:

1) Which PDA with terminal server, VPN, remote access software for desktops is more recommended?
2) Should i go the bluetooth way (bluetooth phone as modem for pda) or a pda phone?
3) what about antivirus software for these pdas?

Thanks
