As per the title. My mac is in my sig, a 2010 Core i7 dual core, has 8GB RAM and a Samsung SSD on the way when it's in stock. So what will I be able to use from the new features? I have an iPhone, I use iCloud a bit but only with the standard free option, I use Googlemail, do not use Facebook or Twitter, and I use Outlook and Office 2011. I play Starcraft 2 and may get Diablo 3 one day, otherwise I use Steam on my Mac so have little use for Game Centre. So will I gain anything from the update? Will it be faster and more stable for me at all? Have their been any report of it reducing battery life at all? I currently run Lion. Thanks for any Answers.
