It seems like every other comment is saying something like "you better not record me or I'll punch you in the face". Why is it that the first reaction these people have is violence, instead of say, ignoring it, leaving the scene, politely asking the Glass user to stop, or even demanding that he stop? While your arguments against Glass may have merit, you're basically bringing it down to the level of "let's beat up that dorky kid with the glasses".

Every post about Google Glass is flooded with comments about "invasion of privacy", "douchebags", "dorks", "hitting them in the face if they try to film me", "blah blah". WTF is this site, Jocks' Central? What happened to "news for nerds"? You don't like Google Glass, I get it. Now GTFO and back to your Facebook to post about what a great fuck your latest girlfriend was.

Ion engines have wonderful Isp, but very low thrust. And it's not just that a journey with such an engine would be longer - low-thrust transfers are inherently less efficient than Hohmann transfers, negating some of the Isp advantage. Moreover, you couldn't reach a nice portion of c with current ion engines: their Isp is good, but not that good. Most of them only have at most a few hundred km/s of effective exhaust velocity, limiting the maximum delta-v to like 0.3%-0.5%c under any design with realistic mass ratio.
