My birthday present to myself: the Apple Watch
First, I bought an iPod. Then I went for the first iPhone as soon as it was launched. Next I obtained the first iPad as soon as it was out. Then I bought the Mac Mini to replace my PC.
Later I upgraded to the New iPad aka the iPad 3. Progressively I upgraded from the iPhone 1 to the iPhone 5 and recently the iPhone 6. Today I went all the way with Apple by buying the Watch. Oh joy!
