As above, my paper subscription for Popular Science has just ended, and I was wondering, since I have the iPad, I might as well go paperless. So here goes. I'm undecided between PopSci+ and Zinio's PopSci. I fiddled with PopSci+ @ an apple store once, and found it to be pretty slick, to say the least. But, the price had put me off from the start, with it being $4.99. But, now it's currently priced @ $2.99 with a slight glimmer of hope that it would roll out it's subscription rates for the PopSci+. Then, there's Zinio's PopSci annual sub for USD$12. Which do you guys have and/or tried ? Any comments would greatly help me make the best choice!
