I tend to favour samsung when it comes to laptops, however:
it's very difficult to determine whether yours is a good one just from the spec sheet. for most uses the majority of laptops will be more powerful than you will need; imo the key to finding a good laptop (or anything of this sort, really) is to find 3-4 good candidates that are within your price range, do what you want them to do, and then scour the internet for reviews.
A quick google came up with this page:

All manufacturers effectively overstate battery life by testing it under the most favourable possible conditions, and maintaining battery life over the life of a laptop is an art form. If you're using wifi, a wireless mouse, the screen at full brightness and are running programs, it should be no surprise that it doesn't last as long as they state on the box.
The second reviewer seems to have more of a clue and has even stated that he's done a lot of research so his opinion should be weighted more favourably, and he likes it for a good few reasons. If you're happy enough with that you should buy it, but as a bit of a tech geek I generally spend a lot more time trying to find out pros and cons before I buy. I build PCs (have built poker computers for honeybadger, mement_mori and others) so hopefully you'll take my opinion as worth something too
