I'm an happy user of the xmarks service and I use it to store and share my bookmarks and my password across my computers (home, laptop, office).
I'm also quite happy of Amazon one click buy system: I can buy stuff from any computer without to get my credit card and type in the numbers.
With the recent breakthrough in the Sony network, I'm wondering if it's a good idea...
Should I stop to use that kind of services ?
Edit: I know it is closed, and I understand why. I just stumbled upon this news that is relevant to this question.

Earlier in the day, LastPass forced customers to reset their master passwords after detecting a "traffic anomaly" that may have been a hacker intrusion.
