LastPass was bought by LogMeIn, which raised some eyebrows. More recently, LogMeIn was bought by private equity vultures. That raises alarm bells for more people.
It was that plus experiencing a lot of bugginess in their apps that got me to switch to 1Password. It's been a huge improvement.
I started moving the day LogMeIn acquired them. Lastpass used to have a very open policy of notification for potential security issues and I trusted them as much as one can trust a SaaS vendor. IIRC LogMeIn completely ignored a number of security issues in their applications and refused to acknowledge vulnerabilities.
