i do enjoy modding, but for the most part i think i'm just way too picky. any undesirable details, no matter how minor, must be perfected. though if someone were to release say a VS or WB that was perfect (in my eyes) in every last little respect, i'd gladly leave it untouched. the closest i've personally ever seen to packaged perfection is Crest (Modern) by ~Leuchtstoff. i even found fault with this though so i purchased SkinStudio just to make a single minor edit to the taskband flash button.
personally, i think there's nothing wrong with being picky. i even think that a sense for perfection couldn't really be called being picky. that Crest theme by ~Leuchtstoff is a real stunner and i always envied those using vista for this one particular design. sometimes it's really killing me that i can't use something just because my system doesn't meet the requirements. so, i can fully understand if you'd buy a certain software just to get that tiny bit closer to what you consider to be perfect.
