I am beyond happy with my decision to make the switch from years of Windows PCs. Within an hour of my unboxing, I had everything set up and working like a dream. The screen is gorgeous, the size perfect for my desk and this thing is just blazing fast compared to my 6 year old laptop! I purchased the Logitech Wireless Solar K750 keyboard and I am so glad I did. I had used the iMac keyboard in the store and it is just too small, and I needed the keypad as well. Love this keyboard and highly recommend it. I am using my old wireless Logitech mouse as well. I will say that if I hadn't been using an iPad and iPhone, I would have found the learning curve much steeper. But, this OS is so intuitive and it just works. /doing the happy dance!
