I have been using the Average C3500 model on trial for 2 days, in order to become familiar with the Tablet PC operating System. I am really interested in the Fujitsu T 4000, but my use of the Avertec has given me some questions. First, how is the heat management? This system I am using is unbearably. hot, and gets hot very quickly. Secondly, how is battery life? Third, how comfortable is it to hold while standing with it in tablet (slate) mode? Fourth, how is the microphone quality. I am a med Student and would line to use it for recording lectures. Finally. how noisy is it? Thanks for any help.
