Although the ship is almost identical to her sister ships, she does have a few small differences. Some of the carpet, wall covering, and furniture colors are different, as is the magnificent artwork and the the look of the Sky Lounge and Cellar Masters. The grand staircase in the main lobby is curved rather than straight, but the ship still has a tree in the elevator lobby. One nice change is that the AquaSpa and fitness center have different entrances. The most obvious differences are two additions -- (1) the iLounge and (2) an innovative new restaurant, Qsine, in the space occupied by the Asian restaurant, Silk Harvest, on the two earlier Solstice-class ships.
Let's take a tour of the Celebrity Eclipse.

I personally think that the Celebrity Eclipse is one of the bet premium-level cruise ships out there in the cruise industry today. As you mentioned in your article, she is very similar to her sister Solstice-Class ships although her slight differences set her apart.
I really liked the concept of the Celebrity iLounge and thought that this was a good move from just a standard internet cafe. I also think that the addition of Qsine was good and offered something that had never been found at sea before.
I also think the Celebrity Eclipse is a very special cruise ship, in regards to the way she began her sailing days, after rescuing thousands of Brits who were stranded in Spain due to the Volcanic Ash-Cloud in 2010; that helped to generate a lot of buzz regarding the Eclipse and many passengers who were rescued by the Eclipse have since taken many cruise vacation aboard her.
