I'll pay you 10 dollars to take my G1.
That said mine is definitely showing its age and I'm excited for my contract to be up this August.
The best phone I've owned so far for functioning as a phone was a RAZR v3. The best smartphone up until about a year ago was the G1, but with limited ram the hardware has been unable to keep up it seems.
If you have a Dream (G1/ADP1) or Magic (MT3G/ADP2?), highly recommended.
