Why not?

1. Price — Starting at $499, the iPhone is expensive. For all the features, it isn’t a bad price, but I don’t want to pay that much.

2. Music & Video — Who wants to watch a movie on a 3.5-inch display? What happened to the 50-inch plasmas everyone wants for the SuperBowl? I read books when on an airplane. And if I ever decide to wear earbuds instead of using speakers for music, I will buy an iPod and a phone separately and save a lot of dough.

3. The Phone — Getting your voicemail in an inbox is pretty cool. It allows you to see all your messages at a glance, and choose which ones to listen to in whatever order you like. Since I use Vonage for all voicemail (cell phone included), I already get this feature, as voicemail is sent via email as an audio attachment. Vonage will even transcribe the audio into text for 25 cents. This iPhone feature is cool, but not really necessary for me.

4. Instant email — I don’t want to have email following me wherever I go. My life is busy enough, and instant “push” email is not a good way to improve productivity. If someone has an emergency, they will call.

5. Internet everywhere — Surfing the Web is overrated and can easily be a time-waster. If I need to find an address with my cell phone, I can send an SMS to Google or call 1-800-GOOG-411.

The iPhone is very cool and Apple will no doubt sell them like hotcakes. However, for my needs it is overkill, and would cause me to be less productive.
