First time poster in on MacRumors. I'm switching over to a MBP in a couple weeks after being a lifetime user of a Windows-based computer. I am an engineer and for the foreseeable future will be using a Windows-based computer, namely the Microsoft Office Suite. This might be a lame, but one of my biggest concerns is the transitioning process that I would have to go through to learn the new Mac Excel 2011. I know exactly where everything is the Windows version, but spent more time than I thought I would have to when I went to visit the Apple Store and played around with Mac's version of Excel. The Microsoft-Apple designers definitely didn't have strict limitations on making the two versions to be close copies, in terms of table structures. In theory, I would like to use Window's Office 2010 on my new MBP instead of Mac Office 2011. However, I'm interested in hearing advice on why this might be a good or bad idea. Is there anybody else that chooses to do this, or are there gains by using Mac's Office software exclusively that I haven't considered? Appreciate the input, and apologize if this discussion has already been made. I couldn't find anything similar in doing research on this website, and wasn't familiar enough with the forums to use all the available search tools.
