Barnes & Noble has slashed the US prices of its Nook tablet and eReader devices in a move that some are interpreting as a safeguard approach to the rumoured arrivals of an iPad mini and Kindle Fire 2.

The Nook tablet 8GB version is now available for $179, with the 16GB version available for $199, having previously cost $249. Likewise, the Nook Color is now available for $149, having originally gone on the market for $249.

Both the Nook tablet and Nook Color eReader sport 7-inch displays, the same size as the Google Nexus 7, Kindle Fire and that the iPad mini is rumoured to house. 

The Google Nexus 7 16GB model is available for £199 and though the iPad mini is unlikely to be available for as little as that, it seems Barnes & Noble has taken the decision to entice its customers with a more attractive price tag, before Google, Amazon and Apple take too much of stranglehold of the 7-inch tablet market.

Both the Nook tablet and Nook Color are available online from, Nook high street stores and other leading retailers in the States.
