I know sentiments like this are expressed in almost every thread, but,
How would this phone change my experience with my current phone? With texting, reading Twitter, taking pictures, looking up the weather? What is there to be excited about upgrading now?
If I purchase a piece of jewelry or a finely-crafted tool for $900, I would expect either to last a long time. These things have smooth metal and glass like works of art, which I appreciate. But I can't afford to treat a phone I intend to use like a piece of art.
I find I cannot be any more sentimental or covetous about my phone, which is essentially a disposable tool to me, any more than Saul Goodman is about his.
