I posted this under 2012 LT, but it still applies.
I work with 2010 at work (Windows). I was excited to finally get a native Mac version and let me tell you, it's disappointing. How can you make an industry standard program and leave features, commands & options out?
It's very backwards that I spend all day at work using the program one way then come home to use the same program except now I have to use different commands and options that are placed in different places. Literally there's basic commands on Windows that have no Mac counterpart.
I read that they wanted to give Mac users a "unique Mac-like experience". Which is nice, except it comes at the cost of a complete butchering of an industry standard program. I want the same behemoth of a program, this is a very poor offering.
Your best option is running AutoCAD on Windows through Parallels. It could look different, sure, but until they add every identical command and even something basic as the new ribbon feature which I can't live without now, then avoid.
If someone can prove me wrong and show me how to add a ribbon and give me a nearly identical Windows experience, then I'll who heartedly apologize, but until then, the next version will be out next year like clockwork and probably nothing will be done.
