*shrug* I don't see any extra clicking, I primarily use keyboard shortcuts and my hands are used to Windows key layouts. I don't want to get into a Mac vs PC debate, but the gist is I really have a deep appreciation for the SteelSeries-designed keyboard on here.
I've got that same laptop. Thoughts: the wireless is wonky, but for me has been less wonky than horror stories I've heard on the internet. It's usable. The trackpad is awful, but becomes tolerable if you turn the palm correction up to maximum. The screen is dreamy and the keyboard is fantastic.
I was a long time ago when I didn't realize it was easily catchable (I was "young and stupid" although I basically just apologized to eBay and promised not to do it again, they let me keep my account and I don't think they would have been so kind these days).
