Honestly, if we see competition(Firefox, Safari, Chrome), Opera should put all its efforts and resources to development ASAP, update frequency is long, and there is so much features that are missing. Every month counts if Opera managers would like to gain some market share .

Good question, the only thing that bothers me with Opera and it keeps me to not stay with it is the lack of password and history synchronization (okay, the extensions sync is not so important)
