I wanted an Android based phone so that eliminated Apple and Blackberry. I was also looking for a newer model.
The three phones I decided to look at were the HTC Legend, the Acer Liquid e and the Sony Xperia X10
After checking specs, Sony doesn't say specifically anywhere on there page, I found that the Xperia X10 was running Android 1.6; a new phone based on an old package. Sony was also the highest priced at $150-ca. It was out of the running for my phone... I'm glad now too cause haven't heard much positive about that phone.
The Acer Liquid e was the cheapest of my three choices at $50-ca. It runs on Android 2.1 and looks good in photos too! I went to Rogers and held one in my hand... seems more like a glossy piece of plastic than a phone.
That left the Legend, once I had it in my hand that was it... this is a phone!
It was $80-ca on a 3 year plan placing it in the middle price range of the three phones but it feels so good in your hand; and runs on Android 2.1 (update expected in September 2010).
After using the HTC Legend for a month I highly recommend it.
