Windows 7's new Taskbar has drawn many comparisons to Mac OS X's Dock, and many of them negative, with the overwhelming concern that Windows is becoming too Mac-like. Even among Mac users, the new Taskbar is unlikely to be universally appreciated, as many feel that the Dock is deeply flawed.
On a superficial level, the similarity is obvious; both Dock and Taskbar are rows of large icons used for application launching and switching. Closer examination, however, reveals that there's a long way to go before anyone should worry that Microsoft is slavishly following Apple. The Windows UI isn't turning into the Mac OS X UI-not yet, at least.
