Opera Mini Beta released; One word, 'Disappointing'

Much anticipated Opera Mini for Windows phone released as beta. People who have signed for the beta few days ago can download it.
One word to say, ordinary and disappointing. No difference between the Opera Mini and Nokia Xpress Browser when the browsing experience is compared.
Opera Mini doesn't follow the new UI guidelines too.
Anyways, detailed review later.
