For our medical staff, we have one desktop on the counter (nice to have the big screen for viewing x-rays, etc) and motion computing tablets. Two of these we purchased new (expensive) and one I got used on ebay. The Doc and CRNP carry their tablets with them, as does the MA.
None of our medical crew can type well, and using DNS would involve developing a new work flow.
We did have our server and computer network professionally installed, and I have to agree with Burt. Hardwired is better. Right now our tablets are wirelessly connected to AC on the server, except when we drop them into their holders, at which point they're on lan.
Hope this helps - all in all we are very (VERY) pleased with AC. Mostly because there's no tricky crap that traps us into a contract or continuing with AC if something better and cheaper comes along (I'm not holding my breath - and they'd have to be really good to get us to switch - we're pretty loyal at this point).
