I know I'm late (way late) to the party but I just bought a very cheap Chromebbook and it beats both of my Windows and mac book i7 machines when browsing the web.

Both my i7s are fast but when browsing the web there's always a period of time when things slow to a crawl when web browsing or the never ending updates that tie them up at some very inopportune times.

I was surprised how smooth and hassle free it is. I use an ad blocker. I will still need my 2 i7s for work but I'm sold. If I'm browsing the web to relax I'm using a Chromebook from now on.

I know most people think of them as less than great but both windows and OSX have gotten so blotted that it slows down even the fastest CPU. Google has done a great job at optimizing the code to work well with low end CPUs. Both Apple and Microsoft should learn from it and create a web only OS.
