My laptop is starting to feel really old and i would like to get a new one but i have also been seriously considering purchasing a tablet later this year. do you guys think a tablet with accessories (keyboard, mouse, stand), could replace a windows laptop for school? i am in college so i really can only afford one or the other but i am leaning more towards a laptop because i need it for school work. I have to write a ton of papers and make powerpoint presentations mostly. any ideas?
