Pros: I put this drive in to an aging 3 year old Macbook Pro, to replace the slow, 7200 RPM drive it had, and now it acts faster (less waiting) than a coworker's brand new non SSD laptop. Time is money, and this is money well spent, that has paid big dividends in time saved.

Cons: As a newer technology, I am a little apprehensive of the early bugs of SSDs being worked out, as opposed to the mature technology of spinning rust hard drives.
