Questions

1. Not sure.
2. No, you don't. But you need an iTunes account to download apps.
3. Yes you can. Just drag and drop them into your iTunes library then sync you iPod Touch.

 

The iPod touch contains an industry standard moisture indicator - the same are found in virtually every cell phone today. Assuming it has not been triggered, or your iPod shows signs of accidental damage, any failure will be covered under warranty for the first year.

In other words, no, they are not overly-sensitive to moisture; sweating and/or humidity are unlikely to cause any harm. Just keep it away from the swimming pool.

 

iTunes is the software you need to download/install before you can sync your iPod, it's what manages the content that you want to put on the iPod.

 

You'll use the iTunes program to synchronize the iPod with your computer (i.e. it's the application that allows you to put your music, pictures, videos, etc. on your iPod).

You can download it for free here: http://www.apple.com/itunes/

The iTunes library just refers to the section in this program where your music is listed.

 

100, 000 Apps available in the app store.
The iTunes Music store.
Fully touch operated.
More than just a music player. More of a pocket computer.

 

That's simply not true. The indicators used by Apple (and as I said before, the entire electronics industry) are very reliable, and only activate when exposed to significant amounts of moisture that would justifiably void the warranty.

Well, the answer will be different for different people. Although, it is the only mp3 player that comes with the app store and iTunes, and has capabilities such as web surfing over wifi. Plus, it's great for gaming, if you're into that kid of thing.

 

Yes, there is an app for just about everything. You can play tic-tac-toe or process credit transactions. Literally everything. Some are free and some cost money; some are expensive and some are cheap; some take up less than a MB, other take 20+. Every app is different.

Yes, you can setup your email too, either using the mail application or by accessing your email through a web browser. It's all very simple, and fast enough.

iTunes is a free download, you could start by giving it a test drive: see how you like the app store.

Also, this website has the instructional guide and video tutorials. They're very good, and I think will answer all of your questions.
