It's a perfectly good laptop and will do all you require.
As said above the blu-ray drive is a slight difference.
Most laptops around the 400-500 mark are pretty much one and the same bar a few minor things such as drives and audio etc, they will pretty much all be able to easily cope with what you need to do on them.
Battery life is pretty much standard on laptops that size you get 2-3 hours, if you need a high life battery then you can look at buying a better battery for the machine or get a netbook - but they're only 10"
Work, Browsing and iPlayer are all very low in terms of their demand so they'll be fine, and ask for the machine not hanging, providing you keep it clean - no spyware etc then it'll run perfectly smoothly
