Yesterday was the first day that Canadian customers of Rogers Wireless were able to pre-order the Sony Ericsson Xperia X10 thanks to a special offer which expires on the 14th of April. Take their guided tour here and see if this phone's specs and the data plans available are what you are looking for.
Unfortunately due to hardware limitations, AndroidCentral reports that the Xperia X10 will not receive multi-touch support in the future, which for many won't be a deal-breaker or a concern.
The Xperia X10 has plenty of good features to it, such as a 1GHz processor, 8.1 MP camera, and a 4.0" screen, but as AndroidandMe says, "the phone is already looking outdated compared to newer Android 2.1 devices." AndroidandMe's article goes on to say that an update to Android 2.1 is expected in the future.
