Well, yeah - Ever since Office 95, the Office UI has always been different to the base OS in some way or another (I think Office 97 was the closest it has ever been to the "stock" Windows UI), but not outrageously-so until Office 2007 came out; Office 2010 is my personal favourite edition because it was the last edition that had a coherent visual design with a fast and snappy UI that didn't require gigabytes of RAM and a GPU to run with reasonable performance, even if Office 2010 cemented the fact that the high-degree of end-user software customization we used to enjoy was now on-the-way-out: now all we can do in Office is choose either Light vs. Dark scheme - and pick from a limited selction of tacky-looking ribbon background images as though we're picking-out a new Trapper-Keeper for the new school-year.
