been using windows 7 exclusively sense christmas, I've been working with it since it launched, and i still hate damn near everything about it out-of-the-box, but the 8gb of ram i got and trim support for the ssd... i didn't have much choice but to switch.
i enjoy more ram, and haveing an actual boot drive, something i wanted for 8 years, but the os i am still fighting every single thing with it.
foldersize, and the cascade/tile options are what i miss the most, i use areo snap, but that is so annoying.... instead of resizeing, it full screens it, but only half the screen, so i cant move the window at all otherwise it changes sizes... as time goes on i am noticing more and more things i dont like, but i got the start bar thing to the point where i can tolerate it and that was by far my biggest complaint. also made the lower right corner show all of the process instead of only a few, that also really annoyed me.
and currently, how files are selected has annoyed me to the point that i made my own thread on how to fix that because i have no idea what to search for.
trust me there are plenty of reasons to hate windows 7, and not everyone can get use to all of its little and VERY numerous annoyances.
