i'm using IE, and besides the fact that it doesn't really matter to me, i switched to chrome and was EXTREMELY let down. i'm not sure what the issue was, but after using it happily for about a week, i noticed that my comp had been slowed to a crawl. i ctrl+alt+del and brought up task manager, just to discover that even when chrome wasn't running, it was eating between 70 to 90% of my cpu usage. i immediately uninstalled, problem solved.
since then, i've reinstalled, even installed some apps on it, use it on occasion, and everything seems to be fine, but for the most part, i reach for IE for daily browsing.
