It has been a very positive experience so far.
You get an office system as part of the package.
Some cases of the spam filter being too aggressive.
I'd move myself if I wasn't so addicted to FastMail's beautiful web+mobile apps.
Not the worst thing ever, but it does seem all Western jurisdictions are ticking time bombs, and thanks to Five Eyes you're at the discretion of the worst one.
I'd consider anything based in the EU to at least be a step above anywhere 5eyes. They at least make an effort towards data privacy.
