I agree they can be useful in certain circumstances (I do a lot of travelling too). I just can't see myself buying one just for the 2 hours a month when it might be useful.
I'm happy to unpack my laptop if necessary and it runs for 5-6 hours without charging. Any minor stuff like reading emails or surfing the web can be done on my cellphone.
I think my main worry about a tablet is breaking it or losing it. A laptop is too big to lose and a cellphone fits in the pocket. Tablets come inbetween.
