Design and build: scaled-down and practical
The keyboard is as nice to use as it is to look at. Keying is quiet and instinctive. Note that the keys are backlit and you can deactivate this feature to preserve battery life. There's also an fn lock key which allows you to lock the function key as active. Great for when you're watching a film and all you need to be able to do is vary brightness and volume.
The touchpad has a nice feel and glide. It looks a lot like the one on the MacBook and also uses the same features (zoom, scroll and so on). You can click anywhere on the surface and the right click can be done Mac style, by placing one finger on the pad and clicking with another.
The webcam gives a good image with accurate colours. Movements do lack a bit of fluidity and you lose detail when in a dark environment but it's acceptable for daily use as long as you light the room enough.
As we said at the top, the finish is up there with that on Apple products but in order to be able to give us as slim a shell as possible, Samsung has used what isn't particularly standard connectivity and this is potentially less practical. Apart from the two USB ports and the headphones/mic socket which are standard, the rest is in mini format. The video out is a mini-HDMI rather than an HDMI, the card reader is for micro SD cards (much less common) rather than SD and the Ethernet socket has been replaced by a connector that is designed to be used with an adaptor to which you attach the RJ45 cable (photo below). Of course, wi-fi is available pretty much everywhere these days, but when it's not, you will need your adaptor. While we've seen more practical set-ups, it still has an advantage over the MacBook Air: plugging this adaptor in doesn't put you one USB port down.

Processor power: slightly disappointing
The processor used in the NP9 - the Core i5-2537M - gives a the sort of performance that is much closer to that of low consumption CPUs (CULVs) than those at the high end of the core i range.
In practice it can handle pretty much anything (retouching photos, 3D modelling, video encoding, office documents, Internet navigation). It's just slower than other ultras such as the Asus Bamboo. We scored it at 78 after running it though our test protocol, which is fine for this type of machine. The MacBook Air 13.3 inch, its direct competitor, scored just 50.
HD video playback (720p or 1080p) is handled no problem by the NP9's integrated chipset. The same goes for video streaming.
The use of an SSD in place of a hard drive limits the storage capacity (only 128 GB) but gives the NP9 good responsiveness, which you certainly notice when you boot the machine up: it takes just 27 seconds and 10 seconds to switch off.
