Overheard in a computer store in Delhi, India #2 - P4 is faster than a P3

Now, this is a bit older but fascinating.

Buyer: Bhaisahab, ek P3 computer lena hai. (Dude, I want to buy an Intel P3 computer.)

Shop owner: Sir, P4 lijiye na. Vo P3 se fast hai. (Sir, you should buy a P4. It's faster than a P3 computer.)

Buyer: P4 fast hai. Kya 5 minute ka gaana 4 minute mein khatam kar dega. (P4 is faster. Does it mean that a MP3 song which runs for 5 minutes in a P3, will last for only 4 minutes in a P4 computer.)
