I can't speak very well to the price/value as I'm in the US, but as far as the specs:
- The CPU is from the previous generation but still an exceptional desktop replacement quad-core mobile chip.
- The display res is 1600 x 900, which is reasonable for a 15" and somewhat standard. 1920 x 1080 is better but can drive the cost up a ways.
- 8GB RAM is good. I'd prefer to know what speed it is (1600 vs 1333), but that's a minor thing
- No blu-ray is a consideration
- 1 TB mystery drive/no SSD, also pretty common
I mean it looks alright but there's nothing really exceptional about it other than the CPU, and even then there's a somewhat improved new generation of mobile i7 chips out now. Looking at this you should be comparing prices against similar notebooks, and then against those that have maybe a newer i7-3610 chip, blu-ray, or better res.
The first one I looked at on Dell UK seems to have better specs all the way around for less money (the Inspiron 15R SE, has new i7, 8GB 1600 RAM, a 1080 screen for £930). I'd expect the Samsung to be better built than a common Dell Inspiron though.
That's just a quick glance but the one you're looking at appears overpriced.
