It's just nothing special whereas the OS on the htc hero is android they are the people who make google, so it's top notch. (as for apps any decent useable app is available for it too, which i doubt you will find for the sony)

Type htc hero demo into google and watch a couple of the video's, in my opinion it's a country mile ahead of any other phone on the market.

As said before I was going to get a sony satio, when i looked at any info all it goes on about is the camera, if thats your bag then go for it. I spoke to O2 a week past on fri and they said they were getting them in last week. ( they may or may not have I don't know cause i went fort the htc)
