My Samsung Galaxy Note Pro 12.2 4G LTE is utterly incredible. It really replaces tablet or desktop with no compromise. It not only does multitasking, but no compromise multiwindowing, has a great experience with the built in S Pen, and Swype keyboard, the large amount of screen real estate gives ample room to sketch, write, view windows, etcetera as I do research. I'm also a musician who does sight reading, and I find that storing my sheet music on my tablet has eliminated the need to carry boxes of dog eared sheet music while giving an excellent viewing experience. Having a 128 gig SD card inside gives ample room for me to store more than 5,000 pieces of sheet music with no compromise. The USB port allows me to plug in external memory sticks or hard drives if needed and if needed, using a Bluetooth connection will allow you to use a keyboard and, or, mouse with the tablet. This Samsung tablet is fast, sure, and reliable as well. I wouldn't ever buy anything less than this. I'm also an invested Android user and since my tablet is almost four years old now, I'm waiting for Samsung to come out with a suitable replacement, but at the present, I use this tablet for everything, keeping records, doing research, producing sketches, writing books, playing music, reading, teaching, and even for entertainment, and witha set of ear buds, and a VOIP account it's even replaced my phone for almost all occasions.You'd have to pry this tablet out of my cold, dead hands to get it away from me. It's indispensable!
