Well then, we won't mention that "by design," it's somewhat irrational to have to click on a START button to SHUT DOWN.
"By design," having the Task Bar encasement be so short that the height of the icons bleed off the top edge, is shoddy, as is having them be too small when "small icon" is chosen.
"By design," having such a large amount of space separating icons not only looks bizarre, but wastes valuable space for "pinning" other quick launch items.
"By design," having 'maximized windows' displayed as buttons in the Task Bar is redundant, unnecessary, and wasteful of Task Bar space.

"By design," "pinning" items to the Task Bar is far more click intensive than necessary.
With the Task Bar, if the application you want to pin is already running, you need to:
Right click on its icon
Choose Pin this program to taskbar

"By design," ejecting devices takes too many clicks.
"By design," most desktop Gadgets are sub-par.
"By design," not being able to run applications outside of their folders is restrictive, and primitive.
"By design," the Control Panel is a cluttered mess:
This is especially apparent when compared to the streamlined, hierarchical organization of System Preferences in SL.
"By design," the UI of W7 is noisy, chintzy, and prone to looking worse than the panel of a poorly packaged 27" iMac:
Windows 7, by design
