As Woodsie said, Apple is trading at a P/E of 12.5. IMO, that's a great price, and assuming they can just maintain their current sales, it's still a good buy. Personally, I think there's still plenty of global growth out there in the mobile device markets, and we will see sales continue to increase. They have more room for growth outside the US, and I think a lot of people overlook that fact when considering Apple.
A lot of people have lost confidence that Apple will be able to keep churning out successful products without Steve Jobs, but I'm not really in that boat. Jobs knew he was leaving Apple and took the time to put the right people and strategies in place to keep his company successful. I am not worried about the company's management over the next several years, and won't be concerned until most of the current executives have moved on. Combined with new, developing markets as other nations start selling more and more smart phones, and I think Apple is going to keep growing over time and earnings will keep climbing.
Don't worry about bear/bull markets if you're investing for the long haul. Over time, it doesn't matter. If you buy and hold a quality company, the price is going to reflect earnings over the long term, no matter what the market is doing.
As for dates, I don't really worry about it. Over 10+ years, a quarterly earnings report is not going to matter. Just make sure they're a good company that you're willing to buy and hang onto for several years.
