It's 1 year old and is the smallest one available, the model has been supersceded by Apple (spec upgrade last July), the equivilent current model costs £850.
This is the International version hence no £ key above the letter 3, it is in good condition and I would take £400 for it (no offers!).
It has the 64GB solid state drive, and as such is silent and cool running. These things are very pretty to look at, are extremely portable and the battery lasts for hours.
If you are considering a Netbook then this is much more capable, has a better size keyboard and (at this price) would be a far more sensible option..
Cut n paste spec below..
The Apple MacBook Air "Core 2 Duo" 1.4 11" (Late 2010) is powered by a 1.4 GHz Intel "Core 2 Duo" processor (SU9400) with two independent processor "cores" on a single chip with a 3 MB on-chip shared level 2 cache running on a 800 MHz frontside bus.
It features 2 GB of onboard 1066 MHz DDR3 SDRAM (which only could be upgraded to 4 GB at the time of purchase), 64 GB or 128 GB of flash storage, a NVIDIA GeForce 320M "graphics processor with 256 MB of DDR3 SDRAM shared with main memory", an integrated "FaceTime" video camera, a non-backlit full-size keyboard (the function keys are smaller, however) and an 11.6" widescreen TFT LED backlit active-matrix "glossy" display (1366x768 native resolution) in a razor thin (0.11-0.68 inch), 2.3 pound, aluminum case.
Connectivity includes AirPort Extreme (802.11a/b/g/n), Bluetooth 2.1+EDR, dual USB 2.0 ports, analog audio out, and video out capabilities (Mini DisplayPort) that support an external 30" display. It lacks internal Ethernet (an external adapter was available as a US$29 upgrade) and lacks Firewire and optical audio in/out as well.
The MacBook Air "Core 2 Duo" 1.4 11" (Late 2010) uses a completely new housing compared to earlier MacBook Air models -- with an 11.6" display and an "inertial" multitouch trackpad -- but also is notable for internal differences as well. Internally, it has onboard RAM and lacks an optical drive, just like its predecessors, but also has flash storage that is not intended to be upgraded after purchase and multiple internal battery cells that likewise are not designed to be replaced. Apple touts that the flash storage makes it possible for this MacBook Air model to offer "instant on" responsiveness and up to 30 days of standby time as well as a thinner housing and improved battery life.
