The Lenovo Miix 320 is quite a good budget computer actually, much better than what the reviews on Amazon state.
Some special features is that it is able to detach into a tablet, has touchscreen, and is compatible with a screen pen called the Lenovo Active Pen. Overall, it is the best laptop in its price range. Be sure to buy the 4 GB RAM version, as the 2 GB version will be too slow.
Size wise, its screen is basically the same size as an iPad. Hence, the Lenovo Miix 320 is suitable for people who want an “iPad with a keyboard”. If the screen font is too small, just setting the system font to 125% will solve the problem.
Conclusion: A very decent budget laptop that is suitable for basic usage such as surfing the web, email and word processing. Value for money (probably the best in its price range).
Alternatives for people with higher budget
The most classic 2 in 1 Laptop is probably the Microsoft Surface. Hence, if you have a higher budget than the Lenovo Miix, probably you may want to consider the Surface instead.
