Its fine to have it on the right side but it would be better to have a preference setting to allow having it on the side user wants.

I end up using all types of systems in the course of a year and having some basic consistency is a good thing.

What I'd really love though is they could fix things like making file dialogs work consistently and ensure dialogs conform to basic long standing UI paradigms e.g. when text is highlighted and you start typing it should affect the highlight text (not a search input)!!

I'm curious how important it is to most people which side the window controls are on. I prefer the controls on the right, but whenever I do use Ubuntu or other systems where the controls are on the left, it doesn't really bother me. If others consider it more important, I'd be interested to hear why.

guess this will make it more natural for Windows users to migrate to it, due to it being the same as on windows

I don't think this is a good change. currently mac has it on the left and their biggest feature user can be mac book pro users that are unsatisfied with the new macbook pro line up and might migrate to dell xps/precision (with ubuntu preinstalled). heck my company is really small and we will migrate to dell's. besides that some things are worse, like the palm control.
