This statement is about a decade out of date. It's almost as out of date as "Macs have a one button mouse."
If you've used iTunes, then you pretty much know how OSX works. Unlike Windows, everything in OSX acts the exact same way as everything else. OSX has better memory management and multicore processing than either Windows or Linux. In terms of security, it's not quite Linux, but light years ahead of Windows.
As for software, Apple software is far better than the Windows equivalent. Windows has Office, OSX has iWork, Windows has Paint, OSX has GIMP, Windows has Windows Movie Maker and Windows Media Player OSX has iLife and iTunes.
Unlike the Windows of Quicktime, the OSX version is stable, faster, and can play any type of media.
Best of all, the average lifespan of a PC is just over two years, where as the average lifespan of a Mac is 6 years.
The only downside to the iMac hardware is that Apple only uses the old-fashion DVD players. It won't do bluray
No, putting Ubuntu on it will not void the warranty. You should dual or parallel boot anyway, Linux is good, but it doesn't have the programs that OSX and Windows have. (Windows programs will run natively on OSX using Darwine, including games. In fact, OpenGL Windows games will run better on a Mac using darwine than on Winodws because it manages multithreading and memory better.)
Both Ubuntu and OSX have very powerful disk utilities for repartitioning and verifing. Adding a second operating system is very easy using either one.
