What the battery life on ipod touch 2nd gen with wifi on? I was planning on buying an ipod touch 2nd gen for only one reason. Its got a good browser experience. How many hours can the ipod touch 2nd gen last with wifi on? I also plan to use it as an ebook reader. Now I know these are not the reasons why anyone should buy an itouch. But I already have a psp which can do video, music and games! But it doesn't to email well. So I'm thinking of another portable device that can do just that! Oh btw I plan to buy a second hand unit again becoz of the reason why I plan to buy one and that is I plan to buy it as a device net-ebook device. Would you recommend me buying one? Or should I consider a netbook for such? Any help or advice would help!
