It is very possible with the current way Apple is going. First off while I despise News Corp. as a company I think a rental system might be fantastic with the Apple TV if quality was there, obviously the growth of that market is going to depend on if the Apple TV can improve and what the cost of the rentals will be but there is a foundation for a great system from Apple offering movies in my living room instantly.
As for the cell market, no doubt Apple may be looking around 2 or 3% of the market in the U.S. before the end of 2008, very small numbers compared to other companies but great numbers for Apple because that number is going to help grow Apple's personal computer market share just like with the iPod. Speaking of the iPod, last I looked Apple was still winning in the Digital Media Player market.
With the MacBook being one of Amazon's top selling items this year, there is no doubt that Apple is going to report growth in their personal computer marketshare. With all of this growth over the last year and room for growth over the next 18 months if Apple shocks us again Jan 15 with some great announcements I can see the stock rising. Apple though is going to have to stay innovative and on top of their game though for this to continue.
