Actually bucking the trend here, if i cant get .com or .net, i like .CC or .TV - i find they are very easy extensions to build into branding, the CC from a graphical nature and the fact its two-of-the-same and rolls of the tongue nicely, and the .TV for obvious reasons.
I find people remember those better than .info, .name, .ws etc because they are easy to build into the brand name. But from a resale perspective, then it has to be .com or .net unless the keyword is a market in itself (sex, casino, gambling, porn, travel, hotels etc).
