My Replenish is on the way, I will be glad to post a review once I have it in hand.
My previous phone was the HTC Hero. I am not expecting any better speed... I am just looking forward to the hardware keyboard. I have realized that I like my work Blackberry for text input, so I think I will enjoy the keyboard even though I will be giving up some screen real estate with the smaller screen.
I also ordered the solar charging battery cover, which I hope extends the useful time between charges.
