In the past two days, I attended two meetings that reminded of this thread. Yesterday, four of us gathered to review a bunch of grad school applications. Each person brought a laptop: I had my Dell Latitude D820, and all the others had 15.4" Macbook Pros. I had always found my D820 very beautiful, but sitting next to those slim and stylish Macbook Pros, it looked sooooo much thicker and antiquated, making me a bit jealous.
This morning, I attended another similar meeting, except the laptops were reversed: only one person had a 15.4" Macbook Pro, and the other three of us had Dells: I once again brought my Latitude D820; another guy had an E-Series Latitude, possibly E6400 or E6410; and the third guy had a 15.*-inch Vostro. The Mac was still the nicest-looking among the four, but I was reminded of one of the reasons I have been refusing to buy a Mac: I want something unique. There are so many different models of Dell laptops to choose from and they all look so different, e.g. the three at our table this morning; by contrast, all Macs look more or less the same. And of course, my D820 has 15.4" 1920x1200, whereas the 15.4" Macbook Pro is only 1680x1050 at most.
