ok, i will do my best to address your concerns. first of all, the more you know about using a pc or a mac, the easier it is to alleviate most of those problems. for instance, if you know how to use a pc, then you would understand that going all the way back to xp, you can turn off, the "user account controls", which is what sends all of the pop up messages. so many people complained about this in vista, when three click's could have relieved the problem. second, expose isn't nearly as nice as the new window funcx's of windows seven. being able to maximise, split screen two windows or shake the title bar to minimize or maximize all open windows is awesome. add to that the ability to "tab + windows" for the flip 3d funcx, and it is a really nice inter-phase. also, the jump list's in win 7 are so much more useful than what i have seen on the new mac systems. my dutch friend has a mac, and we compare all the time. my windows seven is much faster when we use the same programs, and easier to navigate. the control panel is now well organized, and easy to use. another great feature that comes with win 7, are the libraries, which make it possible to link all like files in a single window, which makes win 7 even easier and faster to use.
finally, personally, i put the taskbar on the top of the screen, and hide it when it isn't in use, and have zero icons on my desktop. then i loaded a program called objectdock by stardock, and put it on the bottom where most people leave their taskbar. i also hide objectdock, when it isn't needed, so i have a full desktop when i am working. this setup makes windows soooooooooooooooo much more efficient to use, and convenient in every respect. however, one feature that i really do like on the mac, is the multifinger mouse funcx's. that is a cool feature. while i don't prefer to use a mac, i actually like that mac is doing much better now, because it pushes microsoft to continue to advance to better and better software. competition is always good for the consumer! i hope this helps.
