obviously they are low end as far as studio monitors go, but they are pretty decent. however, the thing to bear in mind about monitors is they are designed differently to hifi type speakers. hifi stuff tends to have a bit of an eq curve of their own, deep bassy sounds, or warm mids or sparkly highs or whatever, studio monitors try to get as flat an eq as possible which makes them often sound "worse" to people when they are used to certain frequencies being more pronounced. it does mean that listening to music will be more like what the mixing & master engineers were working with, and obviously you can get itunes or whatever to add a bit more eq.
when it comes to recording your own stuff they will be more useful as you will have a more professional setup to work with. when using the aforementioned hifi type speakers, their eq will effect the choices you make in eqing and mixing your stuff, if they are very bass heavy you'll roll the bass off a bit or if they are trebley you'll pull the high end down etc, but then played on a different system the sound will be lacking in those areas due to your overcompensation.
so, all in all, yup, they'll be good for you, but they may not be exactly what you expect to begin with.
