I am writing this review with the 8gb iPod Touch. Needless to say the internet browsing is excellent. This site works just as your pc. It also has google earth! As long as you have WiFi at home.
I cannot understand why anyone would choose the iPod Nano over this.
iTunes is a bit fiddly at first but you soon get used to it.
8gb is enough if you have about 150 albums with space left over for apps. The processor is very good with apps running perfectly fine, google earth is just as quick as my laptop. I don't think the 32 or 64gb versions would be worth the money.
The unit itself is very neat and slim, and the battery life is actually quite good.
I thouroughly recommend this iPod.
