I had the G2, thought it was a great phone. However, the screen was too small for me. I felt that the trackpad was a feature truly not needed. The fact that its CPU was clocked at 800MHz to add to the battery life, I am cool with that. However, I would love to behold a dual core beast designed and tailored by HTC.
The GSM Touch Diamond, Touch HD, TP2, HD2 and Mozart are examples of HTC intuition and engineering.
