Pros
Is one of the top Chinese brands to have crossed over from being a Chinese company to an international brand. Still considered one of the best known Chinese brands, in the same category as Ali Baba, Tencent, etc.
Cons
Its best days are behind it now. Clearly the company has lost its way and is now struggling financially. Lenovo used to be known for its bold but smart moves ( e.g. acquisition of IBM's PC division ) but now the management is better known for being self-absorbed and making strategically unwise decisions. The decisions to acquire both IBM's X-series server business and Motorola Mobility in the same year put too much of financial burden as well as organizational burden - neither of these have been successfully integrated at this time. Frequent org changes and strategic flip-flops point to lack of coherent management, make it an unstable work environment. The underlying businesses of Lenovo - IT and consumer hardware - are all in long term decline or consolidation. The company has not innovated in terms of new products (last successful one was Yoga laptops) or technologies. The management team (called the LEC) now feels like a bunch of old people who are increasingly out of touch with both customers and employees, tolerate no negative criticism, are out of ideas and clearly don't seem to understand that they also are running out of time.
