I like how well it can handle multiple devices at once as long there are enough resources for them (cpu/ram). It's not very good when you have many users trying different things simultaneously which leads me think they could make this more user friendly in terms of performance. This would be great if we had better options than just using our own servers or paying $$$ every month so it makes sense from their perspective but sometimes people don't want your solution because its too complicated and expensive compared other solutions out there! We've solved problems such as file sharing between employees who work remotely without having access to each others files via email attachments etc..
