It's amazing. Best laptop I've ever used. Thin, light, fast, gorgeous. You can get adapters for vga, dvi, hdmi and an external dvd drive if you really need one. I borrowed a dvd drive from a friend to install Win7 on Boot Camp but haven't needed it since. And you can easily get a usb hub if you need more ports. I haven't need more yet.
(Public service announcement: this refers to the 256 GB model; the 128 GB model [which I have and find totally good enough for my needs] is @4564. You can now continue your regularly scheduled programming.)
