It was but a few months ago that Apple trumpeted the fact that two million copies of Leopard had been sold in its first weekend. As of Macworld 2008, you can add three million more to that figure. According to Jobs, it's the "most successful release of OS X ever," and nearly 20-percent of the install base has made the leap to 10.5. Oh, and just in case you were wondering about Office Mac 2008, it is indeed shipping today, which means that all the "big apps" for OS X are finally Intel native.
