They will only get lots of passwords from people who are foolish enough to select a brute forcible password as their master. Picking a simple master password is stupid. Storing encrypted data on the internet isn't necessarily stupid.
Not to mention, if you generate random passwords for every service, it's not much labor to just go ahead and generate new ones when situations like this occur. All LastPass clients automatically update to use the new passwords, no big deal.
IMO the convenience of having a central password repository outweighs the dangers. It's a risk, certainly, but not a big one, as long as you have a sane master password.
IE9: 32. Unfortunately that number is from 2 months ago after only short development. At any rate, significant progress is being made.
I use IE9 5 days a week, I promise you it's not the new IE6.
I've found that bing is useful in specific circumstances. For example, try searching for a restaurant in Bing. I find the interface much better, and the conglomeration of reviews to be far more helpful and interesting. This goes for most product searches as well. Bing maps also has a cool feature where you can get directions based on current traffic conditions. Handy for when you want to get someplace when the city is gridlocked in rush hour.
Searching for programming related questions, though, it's next to worthless for some reason.
The reward for working hard is more hard work.
