My local computer store doesn't sell the E2140 because it's only $1 cheaper than E2160. After price cut E2180 should be roughly same as E2160..so maybe E2160 will be drop also. As for when the price will be filter to consummer..that I don't know..We will see next week!
The PC is for someone else, and only use to surf the web/view video..so no need for E7200 but I am aware the Wolfdale is great in power saving.
