MIDI keyboard is very compact and at the same time has large amount of controls, which not many larger MIDI keyboards have. But it has its own minuses : it has no modulation control and pitch bend wheels; it is powered only from USB port and has no power adapter input, so it will draw charge from tablet PCs and notebooks batteries; also 25 keys can become not enough for professional work over time. However, in the role of compact and mobile device Novation Launchkey Mini can be very good, especially if its price in shops is lower than of similar competitors.
