If you're buying a 15.6-inch laptop it's likely you'll want to do a fair amount of typing, and the Q530 should suit anyone well. It keys, which are of the isolated variety, have nice positive actions, and the layout hides no gremlins. There's also a numeric keypad should you need it, a feature that’s become increasingly common on this size of laptop.
Unfortunately things are hampered slightly by the positioning of the touchpad. Because it's slightly to the right of the spacebar, as opposed to directly below it, when typing you'll occasionally find you jog the mouse cursor. It's an irritating trait, and one that can cause errors when typing. There are ways around the issue, such as deactivating the pad when typing or adjusting the sensitivity settings, but the better solution is to put it in the right place in the first place. Samsung have been guilty of this several times of late, hopefully it will hear the message!
Aside from its placement, the touchpad is very good. Its buttons offer good feedback and the surface of the touchpad glides nicely, and supports a range of multi-touch gestures.
Samsung typically has better than average displays on its laptops, and the Q530 is no exception. Viewing angles are still nothing special, but sat in the sweet spot the 1,366 x 768 resolution display generates good detail in videos and photos and punchy colours. If there's a complaint then a higher resolution would be nice, but that's an accusation that can be levelled at 90 per cent of laptops.
Regrettably, Samsung doesn't furnish equal attention to the speakers on its laptops. The Q530 is fairly typical of Samsung's, producing passable audio from its stereo speakers but not much more than that. They'll do for watching online video clips, but for music you'll want some speakers or a set of headphones.
