Yup, I understand what u r tryin t say, but Windows Phone is oriented to EU and US, as well as HSDPA countries.
Btw u can turn Xbox sync and Zune sync off if u do not wish to use too much of ur data balance tho.
The diff of Windows Phone, the essence of Windows Phone OS, is mainly rely on cloud computing and synchronization. If u don't use Live Tile, no Twitter push notification, no Facebook intergration chat, no MSN Messenger, no SkyDrive Office document storage, no photo sharing, no Xbox Live, no Zune real-time personal experience, no push Email, no Tellme voice guide, no Bing Maps, a Windows Phone experience is not outstanding at all, the reason Windows Phone is better sometime is largely bcuz there r so many Microsoft Service behind this platform, supporting it.
It's not when u r using Metro UI, u r using Windows Phone. That's wrong.
