Interesting that a company who simply produces 1 model of tablets, 1 model of phones, a few models of mp3 players, and a few models of overpriced computers has a market cap this high.
Apple will need to continue innovating and selling more than just 10 SKUs of products to hold this kind of value. I personally think the stock is extremely inflated. Sooner or later Apple will need to introduce some new products to hold this high value...the iPod line has been oversaturated for years...that's 25% of their product line...the iPhone and iPad can't carry Apple forever...and my guess is the iPhone has 2-3 years left before everything on the cell market is very similar to the iPhone (Android). If nothing rivals the iPad over the next few years, ok, cool....but then Apple is a company that banks its business on 1 product.
Don't get me wrong...I like Apple...they are obviously on top of the world right now....but it could come right back down to reality ($90/share) in 1-3 years in my opinion as iPhone and iPad competition increases and if Apple doesn't expand its overall Apple product lineup. I am interested in seeing what Apple has in store for tv...if they do it right, that could make Apple some big cash for 10-15 years all by itself.
