I like the idea of replacing a netbook or small laptop with a tablet, but even then Android has some extreme limitations compared to Windows, despite it being based off Linux. I'd rather grab a Microsoft Surfact or Surface RT, the price difference between it and the Nexus are only $100. Well worth it IMO. However, the new 16GB Nexus 7 does look attractive as a portable media consumption tablet, and the new Nexus 4 looks awesome for its price.
