So says the baby who whines about OS's. Sorry, but conjecture doesn't take precedent over actual quantitative tests and browser benchmarking. Maybe if you knew the first thing about web programming you might be able to put that to some use.
Benchmarking........ah yes benchmarking. Let's see now, what in the computer world gets benchmarked? Operating systems (OS) Hardware, ie: Motherboards, Processors, RAM, non-volatile random access digital data storage devices commonly called Hard Drives, Optical Storage Devices and the Optical Media Board Discs they use (CD/DVD/BluRay drive and the necessary read and read/write media, other hardware such as USB 1.0, 2.0 & 3.0, Firewire, IDD, SATA, ESATA, and Thunderbolt as well as other hardware and then there of course is Software. ALL actual quantitative tests. Funny thing about software, such as IE9, FF, Chrome, Safari etc. Here in the 21st Century they all need a OS for them to have the least bit of meaning. News flash. IE9 is not a bootable program. It requires and OS to have any value what so ever.
When a program, any program is benchmarked, the quality and speed of the OS does and will effect the benchmark for the program. Your conjecture that a web browser is the Computer God of the universe is how shall I put it. A load of speculative whiny crap. Thinking that a web browser benchmark is the most important thing in the computer world is like wiping your butt before you poop. It just don't make sense. But then if you knew about computers you might be able to put that to some use. (Oh by the way in case you were not aware, Al Gore did not invent the internet. :lmao:
A new
exploit for IE9 bypasses all security measures in even the latest fully patched version of Windows 7, according to a French security company Vupen.
The exploit uses an unpatched zero-day vulnerability in Internet Explorer 9 and bypasses all the extra security measures of Windows 7. The latest version of Microsoft's operating system, fully up-to-date with service pack 1 (SP1), is vulnerable.
IE9 exploit puts Windows 7 SP1 at risk ~ Hackers Bay
What the world needs, the fastest way to exploit your Windows 7 system.

Hopefully sp2 will solve the issue.
Bottom line, if you understand computer function, as well as programing you would know that there is no perfect OS period. You would know that the use of an OS, hardware and software is a subjective thing to each individual user. You would know that a program is only as good as the collective hardware and operating systems condition at any given time that it is called upon to function and you would know that web programmers are a dime a dozen. That was in pre-2008 financial crisis dollars. Now they are worth about 6 cents a dozen.
