Avantages
Adobe has a set of great product and talent people. You have a solid base to build upon. The culture is friendly and encourages employee to have a good work/life balance. Productivity is the focus not the face-to-face hours. Benefits are good and you can enjoy low employee price of Adobe's premium products, such as creative suites, etc. San Jose office is a green building. The facility is very good. There are many video conference rooms available for you to communicate with teams across the global. Also in the San Jose office, you can access to an in-house Gym with many good equipments.
Inconvénients
There are several downsides here. First, the core business is largely built upon traditional consumer shrink-wrapped software business model. The model is pretty much dead, threaten by free software, open source, subscription, Saas, etc. The company has not found a new growth area yet. Its enterprise product has not found a market segment after four years trying to create one. Its Saas offering faces many other players which entered this market much earlier than Adobe. Its mobile business had a touch year and future yet to be seen. Secondly, the culture emphasizes on collaboration just too much. You can easily have all day meeting without having made any decision.
