Just out of curiousity. If you call these countries Central Europe, what's Eastern Europe for you? (I'm aware that there's more than one truth to most of these vague terms)
This "central Europe" thing is very funny indeed. I've lived in the Netherlands - they think of themselves as "Western Europe". In the UK everyone knows Europe is split into West and East by the Iron curtain.
For me as a Czech, Eastern Europe is everything East of Slovakia - Ukraine, Romania, Belarus. But try asking a Romanian - they'll tell you Romania is Central Europe! When you ask them what is Eastern Europe then, you'll learn it's Ukraine and Russia.
You could maybe consider them the Central Europe of Western Europe, if you want to stretch some definitions :)
Central Europe is basically Germany, Poland and the former Habsburg Empire.
