@TjLaZer:
Well, I'd be bothered with the fact that the battery leaked. Now, if it were a tiny drop that no one could even tell that there was any leakage in the first place, then no problem, however if it were a job that required using an overcoat pen afterwards, then I'd consider the unit not so mint after all. :-)
Don't get me wrong, as long as it works fine, great, however I really appreciate that minty fresh feel as a great extra. :-)
My A4000T looks like that, as if you opened it from the box for the first time just moments ago. :-D
