Kindle Fire starts shipping today...

As Kindle Fire deliveries kick off to enormous consumer buzz (albeit lukewarm reviews), analysts are making optimistic forecasts about the device's long-term impact. JPMorgan's Doug Anmuth expects 20M Fire shipments in 2012, and $8B in total Kindle-related sales in 2013. Anmuth's bullishness on the Fire's adoption has led him to lift his PT for Amazon (AMZN) to $250 from $230.
