Should "i" 3G

The blogs are hot with chatter about upgrading to the new iphone 3G. To be honest I'm not exempt from the thought. After having used the iphone since November '07 I'm more than pleased. (Sigh I'm already speaking past tense) It has truly been the best mobile device I've EVER had. But there is something about the iphone 3G that is tugging at the hem of my pants.  Just brining up the conversation with my wife I get a coast to coast eye roll. 

I'll be the first to admit that it has only been a few months since I've purchased the iPhone. In my right mind, I would never have considered an upgrade just after an 8 month purchase. I'm not one to keep up with the Jones' either. I really don't need to upgrade my hardware every 6-10 months to feel I'm with the "in crowd". So all that said and in an effort to placate my conscience i'll do my best to analyze the situation from a purely fact based approach. Here is my best shot:

• 3G
• GPS
• Upgraded Design - Speakers and such
• The iphone can be a "hand-me down" (It's a glorified ipod touch if you want it for $100. I'll take the first bidder)

So should "i" iphone 3G?
