Can you share a few pros & cons of buying a tablet?

I am considering purchasing a tablet for work and home management, reading, keep track of tasks, etc. I already own a netbook but do not use it as much as it is a bit heavy and cumbersome to carry with me at all times. I am looking for actual owners/users comments on pros & cons., and if it is really worth the investment. Perhaps key questions I should ask myself to justify getting one.

Thanks in advance for your comments they will be of great help since I need to clear my mind and get one or not for the right reasons.
