I'm 10 weeks in on clinics here and we generally have enough computers that finding a free one isnt a big issue. Honestly I have never really wished I had an netbook or iPad while on clinics(and I've been looking for an excuse to buy an ipad). Theft in the teaching hospital here is a very real problem though so its not very practical to have them as there isn't convenient access to secure storage.
My solution has been an iPhone and a thumb drive. Iphone is great for the quick searches you might want to do. And the thumb drives makes it easy to bring documents back and forth from home like templated SOAP's. The phone is also wicked handy for snapping pictures of treatment sheets at the end of the night, so I can write up treatment sheets at home for the next day. Starting the SOAP's and treatment sheets at home save me a lot of time at school in the AM.
