Wow, spaulagain sure is confident in his viewpoint to say to someone "This has to be the dumbest complaint I've heard". Hope you're not in sales or any customer facing business. There is no dumb complaints. More important thing is whether they are common or rare and if it hurts sales.
Again, I personally don't like it. I suspect it's going to be a bout 50/50 with the right brained people (like spaulagain) appreciating the aesthetics of the design, and left brained people preferring a more efficient logical design. Neither is wrong in spite of spaulagain's assertions.
Ideally, what they should do is add an option in the Display settings to include or exclude it. Then everyone is happy and no one is stupid
The new Samsung marketing photo shows the wasted space removed and a full 7 tiles visible. Either they a) agree the Windows design is bad and found a way to exclude it, or b) the marketing guys realized it looks bad and nudged the tiles up just for the photo.
