Suhail came up with a solution to a real problem (Chrome is slow so I get less work done), but just because you don't have that problem, it's absurd for anyone to want this? It doesn't matter if the solution isn't a sexy new technology, or there are cheaper clunkier alternatives, who cares, all I care about is getting more work done. $30-50/month is nothing, if I just get 1 hour back a month it already pays for itself. I know plenty of people who value their time way more than $50/hour - if they can get more work done with a faster browser, getting Mighty is a no-brainer.
Edit: comments like "Maybe rather than having 50+ chrome tabs open, people need to learn how to manage resources on their machines." in another thread drive me crazy. Ok, how are people going to learn this? Are you going to teach them? Statements like that are not helpful because nothing will get done and we will still be at square one.
