Looking to replace my brick (aka iPhone 3G...old school), couldn't be bothered with a new iPhone. Few options at the moment are HTC Desire HD, Sony Ericsson Xperia arc & Motorola Defy.

Keen to go with Android & not Windows mobile etc. Refuse to go with Telstra. Don't want to spend more that $50/month on a cap plan. Storage space for songs etc isn't a biggie - will get mp3 player anyway. Has to have WiFi though.

Anyone got one & can give an opinion?
