Hi I'm kind of new here. I'm really planning on buying an ipod touch. but I have a few questions about safari and a few other things. 1. can I listen to music when on safari? 2. Can I sign into youtube with my account and search my favorite videos? 3. How is the speed on safari? I know it depends on your own connection but is it the same speed as internet on the computer or is it slower? 4. I'm planning on buying the 8 GB one(trying to save $$). now with all the apps in the touch, such as safari and things like that, do those things take up space on your 8 GB. because devices such as the xbox 360 says 20 GB but only came with like 15 GB due to everything it composed of within it. 5. does the touch come with a case? Thanks in advnce.
