I find having the window centered in the scope of the desktop easier to work with, both so I can quickly click on the start button to go back to the menu and because it's much easier for me to activate things inside the PERIPHERY of the wiz screen. Touch screen presses just seem more responsive when you aren't trying to click in the upper or lower corners. I think if he altered the window info bar that would fit in another 5 icons and unless you're just stockpiling programs for the sake of it (archiving) I don't see why you'd need more than 20 on screen icons at the very most, which puts the argument back in your court. Do you actually USE all of those programs regularly enough that using a couple of scroll arrows presents a serious performance hazard?
Again, I side with chp and if he wants to change it then it doesn't really affect my life. I certainly am not going to try and compel him not to do so by making up a list of reasons why I like it how it is now, since it's a very, very subjective argument at this point on your part. I'll continue to use it regardless without complaint because it's far and away the best front end going for the Wiz, fullstop.
