Launchpad gained much attention, both positive and negative, from the press. Clearly inspired by iOS, this new feature provides a grid of application icons that makes selection of programs quick and easy. Or at least, that's the theory.
In practice, Launchpad seems like an odd and perhaps lazy addition to the OS. It's no secret that a computer with a mouse or touchpad has the advantage of far more precise user inputs than a touchscreen device, yet Apple's Launchpad does little to take advantage of it. My MacBook, which has only a handful of software on it, requires three Launchpad pages to show all of the available apps. Why? The icons could have been rendered smaller quite easily, but instead they're large and in-charge, as if Apple expects me to give up on the wonderful touchpad they've provided and start sending my fingers on a stroll across my display.
Another problem with Launchpad is the fact that it doesn't put priority on the user's most important apps. Windows 7's taskbar is a wonderful example of why priority is important. Launchpad simply offers to many options - and with the Dock already available, you may not even find occasion to use it.
Lion's other big new interface feature is Mission Control, and it is excellent. It's long been possible to access a thumbnail view of all running applications on OS X machines, but Mission Control refines the concept and adds to new, static thumbnails of the Dashboard and Desktop at the top of the display. There's also an attractive new linen border that surrounds Mission Control, a small touch that classes up the operating system's appearance.
Unfortunately, despite the improvements, Lion doesn't properly respond to the Windows 7 task bar which remains the best stock app launching solution available on any computer operating system. The Dock remains the same and the Launchpad only serves to add another layer of UI to your computer. Borrowing from iOS isn't going to cut it - unless Apple's way forward is to simply turn OS X into iOS.
