Greatest tech comeback No. 5: Polaroid snaps
Remember those grainy, over-saturated, sepia-toned snapshots you had to shake for a minute as they slowly developed before your eyes? If not, you're probably a fan of Instagram -- which is essentially the Polaroid snap reborn, only without the paper or the shaking. Now of course, every digital camera has some kind of Instagrammy filter built in. Even Polaroid itself recently introduced the z2300, a new instant camera/photo printer that -- yes -- mimics Instagram. Someone call a paramedic, we just overdosed on irony.
