Chrome's launching speed was amazing before SSDs made it so even Adobe couldn't completely fuck that up, and it's update mechanism is still great today. I'm ready for something new though.

These days the back button often seems to mean "redownload the whole page" which shits me just about every time I have to use it, and the address bar likes to just erase everything I've typed when I hit enter and then a few seconds later after it's done some stuff it'll put what I typed back.
