This one was even mentioned on lwn.net today:
You can make a real argument that Solaris innovated more than Linux in the last few years--such as DTrace and ZFSUmm, no, actually you cannot make this argument.
In fact, over the past few years Solaris has spent significant amounts of effort copying the innovations within Linux. One only need to look at their packet filtering and security layer offerings and development.
Solaris still doesn't even have proper TCP Segmentation Offload support, and that's a nearly 5 year old feature Linux has had and network cards have been providing this hw acceleration for even longer.
I hate when I read bogus quotes like this.
