2009: Mac OS X v10.6 (Snow Leopard), WIndows 7

Eventually more information should be collected and analyze the progress in development; some of these have wiki articles but the progress can only be seen from user’s and developer’s perspective. I’d like everyone’s comment on each one of these and if they have used or liked any of these.

Author's note: I’d like everyone’s comment on each one of these and if they have used or liked any of these.

Zico Mathews : Why your list does not include Ubuntu or Red Hat or other Open Source OS. Do you think they have a very insignificant place in the history of OS and thats why you have excluded them from this list?

Zakir Hossain : First of all, they are not really attached with the kernel improvement, Ubuntu or Red Hat or Fedora or such OS are just built on Linux kernel which is one of the most significant operating system kernel developments in the history. But it would be too long if I add a list of time line when Linux kernel is developed, so I wish to give that as a separate write-up. Apart from that if the kernel is not mentioned then “distros” are insignificant for this list.

Tracy Pettigrue : You may add a list of time line for Linux Kernel Development. I hope that would be worth reading. Expecting a new writeup from you on that very soon. Regards
