Pros
There are always really great opportunities to work on neat products -- iphone/os. There are also really good discounts on Apple products.
Cons
There can be a lot of long hours. It's important to set limits for yourself, particularly if you have a family. Training in new technology is often lacking. And when it is provided, there is often no opportunity to use it without transferring to another team. In moving to other positions, it's important to be ENTHUSIASTIC about the job. I don't know whether that means doing somersaults across the floor -- but you can't just have the talent without showing enthusiasm. Still wish there were at least free drinks and maybe a complementary breakfast for early birds coming in to work. Some managers still haven't grasped the benefits of telecommuting.
