For existing Mac users with hardware that can handle Lion, I'd strongly recommend upgrading. Lion is the best operating system ever made, and unless you have a strong reason for using anything else, you owe it to yourself to start enjoying its ease and power.

Mac OS X Lion is definitely a worthy upgrade for all Intel Mac users. Featuring several interface enhancements and useful new features across all the core apps, Mac OS X Lion is an excellent update for the price.

After a long period of relative stability on the Mac, Lion is a shock to the system. It's a radical revision, motivated in part by the vast influx of new Mac users coming to the platform from iOS, that makes the Mac a friendlier computer. Veteran Mac users who don’t like those changes can turn...

Over the past decade, better technology has simply reduced the number of things that we need to care about. Lion is better technology. It marks the point where Mac OS X releases stop being defined by what's been added. From now on, Mac OS X should be judged by what's been removed.

Ultimately the verdict is this: OS X Lion has the functions I need to do my day-to-day work as well as the abilities to drive software innovation and growth through the future. I’ll be using Mac OS X Lion for the foreseeable future.
