Oh those folks at iFixit, they're so wild in their need to take everything apart. Come with me and see their unscrewing and note with me how they find Nexus S to be more of a gimmick than a feature-filled device. Ruh roh. Did they say gimmick? They sure did. They note first and foremost the fact that it's got a curved display and is running Android 2.3 Gingerbread, saying basically that these shouldn't be enough to convince someone to purchase the brand new phone. They do say some nice things though! Or maybe they're just funny. They note that once the back of the phone is off, it looks like something out of Tron: Legacy. Then they say that you shouldn't give the battery to a baby. And you know good and well that it only gets better from there!
Some of the interesting finds iFixit uncovers are on the motherboard: Skyworks SKY77529 Tx Front-End Module for Dual-Band GSM / GPRS / EDGE, SanDisk SDIN4C2 16GB MLC NAND flash, Samsung KB100D00WM-A453 memory package and S5PC110A01 1GHz Cortex A8 Hummingbird Processor (duh, but look at all those extra numbers and letters!), Infineon 8824 XG616 X-Gold baseband processor, Wolfson Microelectronics WM8994 ultra-low power audio codec. Lost yet?
They speak of the smile-screen as well. Smile-screen because it's curved. They mention that Google saying this phone has a "curved glass screen" might be misleading, some people believing that meant it was a curved Super AMOLED screen, which it isn't. As you can see in the photo they took above, the front glass panel is definitely curved, while the rest of the components are as flat as the board. They mention also that the LCD is fused to the front glass panel, making it a bit more difficult to repair should the front panel ever be shattered. Watch out for phone crushers.
