How what can be possible? That I don't like it, or that I'm willing to sell it for $150 off?
I don't like it because I thought I was upgrading from a e71. Turns out the half-baked OS and the lack of apps makes this a downgrade, not an upgrade. (http://talk.maemo.org/showpost.php?p=438257&postcount=6) + no long key press; slow e-mail, unfirendly music player, ...I think I'll get an e72 if I want to upgrade.
Up to $150 off because that I believe that is a fair price to pay for having tried out the phone. However, I may get offers well above the $650, so I may not lose much.
