You can go broke very, very quickly by affixing E and I prefixes to totally random words and then registering them.
I'm actually a fan of quality, commercially viable E and I prefix names (eFlashlights.com, eCondos.com, iFurniture.com) and good, sensible brand types (eDrummer.com, iCalculator.com), but there is a point where they get capricious and just stop making sense (iKumquats.com, iBladeOfGrass.com, eFruitTrees.com, iJiggled.com)
