Bit of a rant here. I received this message today Microsoft. Do you think the average developer knows that “Windows 8 GA” means? GA stands for “Generally Availability”. Put yourself in the position of the Microsoft marketer who composed this message. Why on Earth won’t you just write out the words instead of using the abbreviation? This doesn’t need to be a secret handshake. Granted, if you Google it on bing, you’ll get an answer fairly quickly.
I got my hands on a copy of Windows 8 through MSDN about a month ago and installed it immediately. I’ve used it since then as my daily working machine on my main laptop. First of all the speed of Windows 8 is apparent from the start. Everything feels faster - boot time, application launch, etc. I am working on a 3 year old Lenovo W500 and I can honestly say that Windows 8 has extended its life by at least 6 months.
