$Apple (AAPL.US)$ 
I had been using Apple since iphone 1.
I was so attracted to the product after watching Steve Jobs introduction online, I decided to take the risk to order iphone 1 from E-bay US because it is not available in SG.
After received, I still had to find expertise to jailbreak the phone in order to use it.
I never regret and fell in love!
Ever since then, it had became my habit to change to a new model whenever Apple release yearly.
