Hmm, an iPod is cool, but how cool are you when you get a phone call on your mobile phone, have to pause the iPod, rip the head phones off, answer the phone, etc. etc.
Apple just have to put a 3-Band GSM phone into an iPod to let the cool people remain cool.
You're listening to your music on the iPod, the call comes in, you check the iPod's display, accept the call, the music gets automatically paused, and you speak to your caller. Call over, music resumes.
Which, I hate to admit, means I think BillG's got it kinda right this time.
Bill Gates is Right, and Wrong About The iPod
