We can't say for sure how great a tablet the new LG G Pad 7.0 is -- we haven't had the chance to try it out yet. But if you were already planning on buying the G3 smartphone on AT&T, you might consider picking up the tablet too: Starting on Friday, Ma Bell will throw in the tablet for just 99 cents extra. Now, before you get too excited, there are of course a couple catches. Maybe some dealbreaking ones. To qualify for that insane 99-cent price, you'll have to purchase either the G3, G Flex or last-generation G2, and you'll need to either sign a new two-year service agreement or renew your contract through AT&T's "Next" early upgrade plan. Also, the tablet needs to be on-contract too. Ouch.If perchance you don't want one of those handsets, you can also get the tablet for $150 with a two-year contract, or for $12.50 a month for 20 months, with no money down up front. You could even buy it contract-free for $250, but at that point, we'd encourage you to take a closer look at the specs. For $250, you get an Android KitKat tablet with a 1,280 x 800 screen, 5-megapixel camera and quad-core processor. That's not bad, per se, but for the same price or less you can find similar alternatives, like the Samsung Galaxy Tab 4 7.0; that's going for $170 (down from $200), with mostly the same specs, save for a lower-res camera. That's not to say you shouldn't buy the G Pad -- just that you should do your homework first.
