I will admit I don't understand all the techie terms, & why one thing may work better than another - I just wanted a couple of tablets that will keep my daughters happy & didn't cost the earth. I believe I got that :o) Items arrived VERY fast, & do come well loaded with apps to save me time & effort. It found the WiFi within a moment, & I have checked the speed by watching You Tube vids, also instant with no waiting on buffering time (often takes my pc longer!) I can't judge what another may use a tablet for - but for our purposes (mostly games & fun time, the odd movie, with an occasional homework assignment thrown in) I believe we made a great choice. On top of that, the seller went above & beyond with helpfulness. Many thanks!
