Tagging entities in review textUsecaseI wasnt really in the market for another tablet, but my girlfriend endedup getting one for me so she got me on this one. I would like to say thatthis tablet reminds me of the first Motorola Droid smartphone that cameout several years back. The phone jam packed a ton of bells & whistlesinto its hardware and software to give a lot of bang for your buck. Thisis what it feels like amazon has done with the Kindle Fire 8.9. They haveput a lot of advanced hardware and innovative software, so for theaverage user, specially someone who absorbs a lot of media, you get alot for the price. But just because you get a lot for the price, doesntmean it is without its flaws.
