If you have a PocketPC and you want to read CHM files (compiled HTML Help Format - previous MS' help format) on it then here is the solution. Pete's free CHMReader does the job very well and the result is actually very readable. I read every issue of MSDN Magazine (free CHM downloads) on PocketPC while I wait somewhere (don't you hate waiting at i.e. doctor's doing nothing?). Plus I have a copy of LLBLGenPro's help file on PocketPC, too. Very useful at the start since it is not just a help file, but also a guide to OR mappers in general.
Almost forgot - this is my first blog entry with Windows Live Writer.
