iPod Touch? Or is there another option...?

[emzy]

So I'm wanting an iPod touch to be able to play with the wifi - check my emails, use online dictionaries, play on facebook and youtube etc.

But are there any other options, like other makes of MP3 players, that will do the same job?

Or any wifi-enabled phones that would be cheaper than an iPod touch?

Failing that... does anyone know of any iPod Touches that are going cheap?
