Should I buy a trackpad?

Solution 1:

I have both the Magic Trackpad and the Magic Mouse, and IMO the trackpad works really well for browsing, navigating in the general system, and is a very natural way to interact with the computer.

That being said, it is not precise enough to be used when you need to do photo/video editing, and in those rare occasions I use the mouse.

I also do programming, but barely use the mouse/trackpad when I'm coding.

Pros:

• Very easy to navigate in pages (Web browsing, preview, etc.)
• Enable one to use the built-in gestures, and that make a huge difference in day-to-day computer usage
• Ideal for an "HTPC" usage of your Mac : I frequently casually use my Mac from the couch, and not having to move a mouse is a definitive plus.

Cons:

• Precision
• Doesn't fully replace a mouse
• You'll miss the gestures as soon as you'll use a different computer.

Solution 2:

As a web developer as well I use the Magic Mouse and get almost all the functionality (gestures) in Lion with the benefits of precision when I need it. I used the Magic Trackpad for a while (borrowed from a friend) and it didn't work as well for me compared to the Magic Mouse.
