At my husband's company, they just got a set of Nexusses... (the 7" one). Every single one his colleagues that was playing with it said: I like the size better than that 10"! Naturally, I've been saying that for 2 years already...
At home, we both have our wifi 7" tablets (HTC and Lenovo) and we're both very happy with it. But they'll never ever replace our desktop PCs.
