I have been searching high and low for a device that I can use the touchscreen capabilities of OneNote without breaking the bank. I really like the Surface 4, but I am not in the financial position where I can drop $800 on the tablet and another $150 on the keyboard. Currently, I have tried taking notes on my Lenovo Flex 2 and my Samsung Galaxy Tab 3, both where hamydowns that I took because I thought they'd work for taking notes, but neither can even come near to being usable. The two main problems are that it is hard to draw continuous lines, and there is no easy way to switch the writing instrument so it is easy to fall behind while the lecture is going on.
Is there something out there like the Microsoft Surface, mainly concerning the OneNote integration, that does not have such a hefty price tag? My budget is around $500, and pen + keyboard inclusion is a must. It does not have to be a Windows device (Android would be okay too), but it needs to be responsive enough that the device lag won't be a hindrance on note taking.
