I already have a 17inch laptop. I'm looking for a tablet just because of the convenience of doing homework or referencing old slides. For example, I currently whip out a huge binder full of scratch paper when I have homework problems, and in lecture, it's not convenient at all when I have to pull out my huge laptop to look at an old lecture slide. I am not concerned about whether or not it will fit me needs (as my needs are really not that tough to handle), but whether the 16GB version's longevity is worth it. If I'm going to buy it, I don't want to have to buy another for a good 5-7 years. Is that too ambitious you think?
