I used to post more, but the politics usually pushed the threads off the front page.
Yup - Apple was a good call. My wife bought a thousand shares or so several months ago and its paid off nicely.
As for what I invest in - just about everything. I try to keep enough in savings that my wife and I can go a couple years without having to work or dip into any investment accounts. We keep a slush fund for speculative investments (like those Apple stocks) that we'd be dissapointed to lose, but has no bearing on the long term plans for retirement. Our retirement accounts (SEP, 401Ks and handful of Brokerage accounts) are built for aggressive growth since we are still a few decades from retirement. A wide veriety of choices in there.
If anyone is thinking about getting into the market - READ READ READ! Read up on the companies history. Read reviews about the company. Pay close attention to any turnover in management. Read about their long term plans. Read up any litigation they are in. Read up on any government interaction with them (any government in the world). Investing into a single stock is like gambling. Don't put in more then you're willing to lose.
Diversify. Almost all major banks have retirement calculators. Use them. See where you are at or what you need to do to get where you want to be.

While I've bought my fair share of cars, we generally don't buy many things that lose value (beyond necessities). We want to be retired and travelling the world before we're sixty.
