There's no wireless internet at the ICU, in fact, no wireless devices are allowed in the unit. When I'm in the waiting room, however, I'm able to use my Sprint Treo 650 and PDANet to replicate Lotus Notes to my M4 Tablet PC.
Once I'm done replicating, I can walk back into the ICU with my tablet and process off-line. I'm actually not doing much in the way of processing anything lately, but at least I have the systems in place to do it if I wanted.
SprintPCS has a $15/month all-you-can-eat data plan and the PDANet software is $35. That's all you need. It's not as fast as an EVDO connection, but it allows me to surf the web, access my servers with PC Anywhere, and replicate my notes databases to pick up my email, faxes, and voicemail. I don't use it often, but when needed, it's been a valuable tool.
On the subject of cool tech in the ICU, lots of cool gear here. As long as I'm here, I'm going to explore and learn. If there's interest, I'll even come back and take some pictures of what I think is the ultimate Tablet PC (or book) accessory to show you....
