Re: Client support, we've heard about it
Welcome to the real world, where your new computer comes with Windows 10, as opposed to the Windows XP found on your old computer. Or HP Unix instead of Solaris. Or the new ribbon interface on Word. Heck, the user interface on my first CD player was radically different from the UI on my mom's phonograph. Maybe we should dump on the CD player manufacturers?
Change is the only constant in this world (well, that and the presence of idiots).
Part of the problem is that we don't really train our end users properly. We teach them that to do task X, you click here, then you click here, then you click here. They don't understand why they do these things, or what each step accomplishes; they only know to blindly follow a sequence. Part of the fault belongs to IT. Part of the fault belongs to training. Part of the fault belongs to the users' management. And part of the fault belongs to the users.
