After dabbling in Office apps since the days of 5 inch floppies I can sympathize with the sentiments being expressed. I think we get comfortable with the interface of an app and grumble when they "improve" it because the familiarity of it has to be re-learned. For me, the introduction of the ribbon was the most perplexing thing, which they no doubt introduced just so that all my menubar code and knowledge gained around that could be relegated to the trash heap. That was closely followed by all the changes in Word and Excel which were surely introduced just to confound the likes of me.
I could hold onto that premise or accept that change is here to stay and try to understand what drives it. It is easy to overlook the benefits of change by focusing on what we don't like that changed. AFAIK, beyond the calendar control and the ability to edit a linked spreadsheet (the latter being lost as the result of a successful suit upon M$) there isn't much in Access that was lost. It is more likely that to get to it takes a different path - and what we really don't like is having to learn a new one.
Hope that helps a bit.
