Thank you for all your replies.
Its definitely given me lots to think about, the laptop i have is older than i thought so not sure its worth spending money on, dvd drive not working, battery and charger not the best and worst off all taking around five minutes to boot up, and sometimes stopping when loading pages and just beeping loudly if not left to take its time.
The chromebooks really appeal to me in that it will be quick, continue to be quick and seems to fit my requirements well.(not sure about printing and word docs etc, But and its a big but perhaps its better to spend a little more and buy a laptop?.
