I recently bought a cheap&small office laptop with intention of taking it with me and completing assignments in public places. Problem is, it chokes up and dies when running more than eight tabs on firefox. I also tried k-meleon, it has great performance but the UI is ancient and many websites that I need dont support it.
You will be surprised to hear that the number of people who keep a bajillion tabs open is very high. At my last job, majority of the people I worked with did that.
