Brian Caulfield on Forbes:

Does the gigantic iPod iPad have USB ports? No. Flash support? No. HDMI output? No. SD Card slot? No. Can it run several different third-party apps at once? No. Will you ever need to clean the registry and defragment the hard drive? No. The iPad sounds silly if you’re shopping based on features and specifications.

Add to that no viruses, no malware, no complex anything. The money quote:

Make a PC really small and it kind of sucks. Make an iPod really big, however, and it’s kind of great.
