I've bought motorbikes and laptops using Bitcoin, I've also repaired houses and set up a grocery store using Bitcoin.
My estimate is to spend about 1 btc for the above purposes. I am quite happy because at this time the grocery store assets, motorbikes and laptops are very useful to earn more income.
I have not directly bought any items with Bitcoin but yes I do remember I bought things converting Bitcoin into my local currency and bought a memorable item, Golden Ear Ring to my wife. I have earned a bit bitcoin from here and yes I used it. Besides this, I use the money converted from Bitcoin, for my basic needs as like everyone else does. I try to save some bitcoin often.
