My wife is a part of my heart, I'd say a bigger part of it.The only reason i would buy it is because i love it. It is part of my heart right now.
My daughter has her corner in it, and my parents, and my friends.
My phone, as my bike, is a piece of machinery. I can like it more or less, but I don't grow attached to it. If it breaks - I'll pity the money lost, and get another. If it annoys me and I have enough $$ - I'll sell it and get another. Nexus was good, it served me well for a year, but it annoyed me a bit too much
For comparison, when playing today with newer devices than my MT4G, I don't feel any urge to upgrade. Nothing really worthy in Sense 3.6, and nothing really missing on my phone. I'd probably live well with Desire, too. So it leaves the crappy touchscreen to blame - everything else can be dealt with.
