Outside the German (speaking) market AVM doesn't matter much. And looking at the tiny selection on the German version of http://store.google.com, the German market doesn't matter much to Google.
That's market segmentation at work, and OnHub likely won't be a threat to your favorite DSL modem brand (and it isn't a DSL modem, btw)
And what we’re seeing here is that a lot of people say "this router is awesome", "it does so much and is so cheap", "there’s no other router with that performance", and I’m just here, facepalming.
It’s an upper-mid-range device in an oversaturated market, not something worth hundreds of reviews and articles.
Tbh, I don’t care about AVM – the Fritz!Box 7490 was just the first router I could find with a similar featureset and similar price.
Also, the Google Store is even more empty in many other countries – US, Canada, sometimes UK, NZ and AUS get the nice products. Some european countries still have no Google Books, Google Movies, Google Music, or even the ability to buy Nexus devices.
