The small screen, iOS, content consumer devices will always be more important than the large screen, OS X, content producer devices because the market is much bigger. Macs are now a minority business for Apple.
But that doesn't mean it isn't profitable or that it is going away. Fact is it is growing, and without any real effort on Apple's part.
iOS-like features in Lion, like LaunchPad, may be annoying for the Mac Faithful, however they don't have to be used! But the important thing is that they will lure into the Mac fold people who have an iPhone or iPad and a Windows PC. They are having a good Apple experience want to carry it over to their computer.
Some state that the professional market is small but this is a misrepresentation. Having worked in an architecture and design firm, we had 23"-30" CCFL LCD ACD's paired with PowerMac G's. Our small firm had about 20. Do the math. Businesses invest in bulk, lots of money. For example, Annie Leibovitz. My friend Rich was a photography producer with Vanity Fair/Vogue. Annie only used powers systems and OS X and ACD's due to their near perfect color accuracy. Now, I've been told she's transitioning away from Apple.
Dismissing any market is bad business. Apple can make bank from businesses just in volume alone. Perhaps this was due to MS's dominance of the business market and that most businesses will only invest in hardware they know will be covered as Apple has a history of keeping their market plans and development under wraps (Apple employees don't even know what their own employer is producing), which makes investors weary.
Apple hasn't added much needed features for professionals in Lion, much due to their focus on adding and perfecting consumer features such as the iOS "Launchpad." Apple has yet to work on OpenGL 3+, Resolution Independence was dropped in 2007 when it was included in a few of the developer beta's (and yes, it is possible, it's been done and Apple has had plenty of time to make it work), Xserve is gone and Apple will no longer support it leaving businesses who invested thousands screwed, and I don't care if mobile devices are the future. We NEED larger displays for work. Heck, my dual 24" setup is sometimes not enough when I'm editing in Final Cut Pro.
So there are two sides to this coin, and I agree on both, however Apple is dropping the professional market too soon. It's not a niche market, companies invest thousands in hardware and such. In fact I convinced a few businesses in NYC when I worked in Communications to go with OS X/Apple. They spent ~$20,000 for ONE small business. Had I known Apple's future plans, I would have recommended Windows NT
However, dismissing the professional market isn't a solution. Apple revamped the mobile market, they have billions, just a small amount and they can lure businesses in with a more secure OS and solid support and hardware.
