It is a great chart, but you have a bit of a naming / branding problem because of your versioning – it looks like the premium product isn’t as recent or updated as the personal product.

You might consider making this Tasks Pro a 2.0 release – it goes against engineering sense, but makes perfect marketing sense, and I suspect your installed base would be ok with it. I once read a deposition of Bill Gates about the versioning of DOS, where the lawyer asked him what the rationale was for point releases vs. whole number releases. He had a one word answer: marketing.

You might also want to play with the naming a bit to make the distinction clear – how about “Multi -Task” for the multiuser product or “Personal Tasks” for the personal tasks.

Hope these comments are useful.

Thanks,
