Pros
Pro Choice of hardware
Linked above is the classic bulb style, but Osram offers a few different products that fall into its Lightify family of products. These include an RGB flexible strip of LEDs (really cool desk/counter/home theatre accent lighting), and two other cheaper bulbs that don't offer RGB lighting (one has adjustable color temperature, the other doesn't).
Pro Access to 2 major ecosystems
These bulbs aren't attached to their own proprietary ecosystem - they are built to be compatible with Wink and WeMo which are already established ecosystems which allow for third party automation as well as other features.
Pro Very efficient
While any LED will be more efficient than incandescent bulbs, the Osram Lightify is one of the most efficient smart bulbs currently available, providing 89 lumens per watt (beating WeMo at 87, Philips Hue at 81, and GE Link at 78).
Pro Inexpensive
At just $15, this is one of the most inexpensive smart bulbs available. It's great not only as a first step into smart bulbs, but also as an inexpensive addition into a Philips Hue or other compatible bulb system.
Pro Many options for automation
Robots is an easy to use automation tool that lets you take control and create your own recipes for your bulbs to follow (flash blue when you receive a text, flash red when the door opens, etc). Shortcuts are also supported - you can setup a cluster of lights to all enter a pre-determined mode with the touch of a single button. Also supported is scheduled lighting - you can have the lights dim near bedtime, and start to illuminate in the morning to help ease the sleep process.
Pro Compatible with many ecosystems
At launch it was only compatible with Wink, but since then has added Staples Connect, SmartThings, and Philips Hue Bridge support. This allows for a wide range of hardware (at varying prices), as well as your choice of ecosystem.
Cons
Con Lacks polish
The app isn't as intuitive as the other higher-end competitors, and lights have a slight delay when turning on.
Con Short lifespan
While virtually every other smart bulb is rated at 25,000 hours, the Osram Lightify is only rated at 20,000 hours. While it isn't certain these lights will clunk out before the others, it seems more likely.
Con Below average color rendering
The colors that the Cree connected provides are just below average for smart bulbs. At 80% of the spectrum, they fall behind the GE Link (90%), Belkin WeMo (88%), and Osram (81%) but a hair ahead of the Philips Hue (79%).
Con Hub required
You will need a hub, but at least you can pick your choice of hardware from cheap solutions ($30) that just control the lights to $50+ systems that can be the brains for your whole connected house.
Con Poor lightswitch dimming
As with all smart bulbs with in-app dimming, dimming from a lightswitch provides less than optimal results. The two dimming systems both try to take control, which results in flickering and some buzzing.
