At first glance, this quote by Windows Manager James DeBragga doesn't make much sense. But it's actually a relatively reasonable metaphor.
He compares Android to a puppy thusly: sure, you can get a puppy for free, but then you've gotta housebreak it, take it for walks and train it. It takes a lot of work to turn that puppy into a properly-behaved dog.
And really, that seems to be true based on the initial experiences of Nexus One owners. But then again, that's one specific case. Every mobile platform, including Windows Mobile, has its issues. Are Android's really worse than most? [Laptop]
