Is it just me?

Having read multiple reviews of the 15" rMBP, I was under the impression that the display represents a big leap forward. Long story short, I recently got a 15" rMBP from work, and although I absolutely love it (so fast and shiny, highest end i7, 16 GB RAM and all that), I don't see what the big thing with the screen is. Seriously, IMO in practice, the 15" rMBP screen doesn't look that different to a 13" MacBook (early 2008) screen..
