I have XE2 and like it, but there seems to be almost NO documentation for new features.  I have no idea what all these new additions do such as Fastscript, Indy, websnap, IW .... etc is or does. 
 Do you expect people to waste days searching for clues on what these do ?  Poor  or non existant documentation is a major problem it seems.
