Upgrades. What a thing to be worried about. What does that mean anyhow. To me it implies that what you have now is never good enough because what you could have in the future is better. I don't think that's any good way to live your life. You're always thinking about what could be instead of what is. Not to mention the fact you can't ever enjoy what you have right now. It's a losing uphill battle that you can never win. Upgrade when something is broken, not when you're bored with it.
