Critical I see: a fall I would not want the laptop in the sleeve, because no buffers are available. Aussderdem the simple Velcro probably will not last forever and must eventually be replaced.
Good would be even a side pocket for paper or similar
The bag does not let chalk up the internal dimensions and the tight fit with my laptop: a Lenovo Thinkpad Edge E145 with the dimensions (mm) 23 x 287 x 212 fits into it, but at first glance, the laptop is a little too deep and slightly too thick so that the Velcro covers only to 4/5. Through frequent use, the material expands a bit if necessary.
Conclusion: looks good and protects properly when traveling to another packaging such as a suitcase.
