Here's the bottom line....

You really won't need a laptop anymore....

I have a similar phone (Sprint Mogul) and it has changed the way I do things.

I'm a teacher and a coach....

I get my school and personal email on it...
I get my latest sports scores on it
I get the very latest weather.
I text message my entire HS JV and Varsity Baseball Team on it----all at once---tremendously effective
I watch TV on it
I listen to music on it
Reminds me of all my appointments
It replaced a very good GPS system I had mounted in my car
I use the built in camcorder to film my team hitters----then play back the clip right on the field (we do have to find a shady spot to see it)
Synchs wonderfully with Outlook and Vista

And---oh yeah---it's a great phone.....

I have read somewhere that it can be done (limited) as it has basic internet capabilities....

You would either have to RDP somehow into the WHS.....or the router....

Do a google on it and see what you can come up with....

Also two very knowledgeable forums are

Good to know----thanks----since I have a HP MSS WHS at home----would be nice!!
