The speakerphone sounds pretty good - you can hold a conversation with it with the moonroof and windows closed while going 80 on the highway. I would recommend getting the walk in express insurance if you get Nextel. For $1.50 a month, you can exchange your phone no questions asked. I've replaced 3 phones already (dropped it a few times, and had 1 speakerphone that didn't work too well.

Here's another pic of the cell phone and $25 install kit:

I have my complaints, but I think all cell companies are the same. Overall Nextel's been pretty good for me.

Nextel's had great coverage everywhere I've travelled. The speakerphone on the i1000+ works great when mounted in the car holder. I can have hands free for $20 bucks instead of the $1000+ for the CPT8000. Although I would love to be able to use the buttons on my steering wheel!
