why does Apple put "i" in front of all their products?

[Kyros]

so then why did they call it Apple Tv

Because EyeTv was already taken .

I think its pretty cool. If you look at the trainwreck that is naming in big companies. Motorola ROCKZXZR,
SONY BPD-500IZUV
I am not even starting about Microsoft

then iPod, iMac, iTunes is a pretty cool naming convention. You have one word, you know its apple and it clearly says what the product is. Rather cool.
