The amazing Tom's Hardware Grand Prix lost prestige in my eyes when it decided to not count memory use in the grading. Those who are stating "Memory is there to be used" are the ones whose favorite browser uses so much of it (I won't name names, but it's a semi-official meme on their forum). Memory is there to be used... but not solely by one program, unnecessarily. On modern operating systems, all extra memory is used for caching of previously loaded programs, disk buffers, etc. and has a noticeable benefit on performance. A browser that eats up, and refuses to release, all of this memory degrades the performance of the system. Additionally, few systems are only running one program at a time. Using gobs of memory is going to force other programs to swap memory out to disk, also negatively impacting performance. No one would give Excel or uTorrent a free pass if it grabbed 1.5GB of system memory; why do this for a browser?
I also have to take issue with the claim that browsers are adjusting their memory use based on installed memory; this is another dubious claim put forth by fans of a certain browser that starts with O. Turning off memory caching in that browser still results in the usage of large amounts of memory that is never returned to the OS. It's also probably swapping a lot of memory out to disk.
