No, I'll wait what Jolla comes up with. If it's a Sailfish version without Dalvik, then they didn't create a worthy successor for the J1, so I'm not sure if I'll spend that amount of money for a just-not solution.
It's like buying a Ferrari with small/narrow wheels.

But who knows: At this moment I'm having a subscription with different telephone number from where I work and I can integrate my works email on an Android phone. I'm trying a Galaxy S3 at the moment, but that's not quite fast. The Experia could be an option.
