Samsung Tablet Loathing

I am a marketing honours student completing my 4th year at the University of the North West and I have had more than I can take with my Samsung Galaxy 2 10.1 Tablet. As a student I generally don't have loads of cash to just toss my current tablet and buy a new one because I am dissatisfied with the poor quality device that Samsung has provided me with. I took a gap year after school to work and essentially earn money to simplify my following year at varsity. Before I commenced with my studies I used my money to buy text books and a Samsung Galaxy Tab 2 10.1 which I did research on and I thought it was the ultimate, the tablet device leader in the market, costing me 4 years ago roughly R7000-R8000. It went well for a couple of weeks and then my hell started, the device is slower than a sloth and worse than that constantly stalling requiring me to format the device, resulting in me loosing all my work which I have saved on the device. This issue has required me to format it a couple of time over the years and know it is only a R7000 electronic that lies and accumulates dust. I have thrown away thousand of rands I cant' get back to have little to know contribution to my academics
