Tablets are wonderful little machines for two sorts of people. First, those who aren't heavy computer computer users; the grandmothers of the world who check their email once a day. The tiny screen and on-board keyboard are no major inconvenience because they don't use either enough for it to become a significant problem. The small form factor means the tablet is easy to tuck away when not in use (unlike the big bulky computer which dominates whatever corner it sits in) and its uncomplicated OS makes it easy to use. The other group are people who want it solely for media consumption, whether that takes the form of watching a movie, listening to music, reading articles on the web or playing uncomplicated games. Some of this latter group will also have a proper computer and use the tablet as a supplementary device.
The right tablet is also a wonderful little machine for a businessman, especially a business traveller. The Samsung Galaxy Note Pro 12.2 is roughly the size of an A4 sheet of paper. It has displaced my notebooks. If anyone is still using a daily planner, it can displace those too. I now do the vast bulk of my writing with a stylus. I will be able to keep all my notes on the tablet (with optional external backup) for the rest of my career, instead of having just the last month or two and nothing beyond that. So that's awesome right there. For anyone who takes handwritten notes on paper, this is potentially a killer app.
If I travel I can connect to the company servers, I don't have to use apps locally. I can email, which is one of the main uses. If I really need to do something in an office suite locally, I can use the openoffice port for Android. I can get a local microSIM so that between the Note Pro and my phone, I've got internet. And for travelling, I can put the bulk of my documents on the Note Pro, which makes it really convenient to travel with hand luggage only because my IT and document needs are contained within a small, flat volume well within a kilogram of mass. All I need to charge it are the USB cords and a dual USB charger that handles the 2.1A for both ports, for phone and tablet.
So you can see that there are several points where the Note Pro is more useful than the Surface Pro 2. Bigger surface that is closer to proper notebook size, no special charger required, you can use one of those portable USB batteries for your phone and your tablet. MicroSIM for internet. Somewhat longer battery life. Android Play Store. Many of the professional reviews completely miss the point of the Note Pro and say that it is too large and costly, despite the fact that it can do most/all of the relevant tasks of laptops, has similar screen size, and is thinner and lighter than any of them, while being less expensive.
Samsung, if you are reading this, you need to improve your clunky access to S-notes. I ought to be able to read the full titles to the notes, with a date and a title, without truncating the end. The default title with the date also should optionally be year-month-day order, e.g. 20140424-note_title, so that I can sort/browse the list of note files in chronological order. And also, I want to devote a whole desktop to just notes, so that I can quickly search through them. Rather than the measly quarter window that is all that you allow me to dedicate to the task. And this note browser should allow some sort of detail/list view rather than the myopic large icon view that is the default.
Another thing that ought to be available is the ability to convert the handwritten notes into a text stream for searching. Shouldn't be that hard considering that the order the stylus strokes were laid down is probably recorded. It won't be 100% of course but would still probably be useful enough for search.
