Summary: I just discovered that this is a common bug and Intel refuses to issue a firmware update to fix. They don't recognize that there is problem. Symptom: while browsing the web in either IE or Firefox, my T61 freezes for approx 30 seconds. You can't do anything until the system unfreezes. It's random, but seems to be more common early after a system start up.
Pros: Standard benefits of SSD vs traditional HDD.
Cons: Randomly freezes while using web browser (doesn't matter which one)
