Your Mac Should Be Like an iPad
The message from the Back to the Mac conference was very clear - Apple is happy to go back to the Mac, but only in order to revise it so that it is more like the iPad and iPhone.
Virtually everything that was announced at the Back to the Mac conference, the new iLife 11 suite aside, was focused on lessons learned by Apple's experience with iOS. The App store is coming to the Mac, the new MacBook Airs will be using flash memory instead of a hard drive for storage, new iPad inspired interface features will be introduced, and etc.
Some of this is promising. The App store, in particular, could be a good thing - although it will be interesting to see if the introduction of a Mac OS X app store has a positive or negative impact on the overall quality of the programs available for OS X computers.
Other decisions are not as promising, however. The switch to flash memory offers nothing tangible for consumers except for laptops that are slightly lighter and thinner than what is currently normal. That would be huge improvement if today's laptops were too heavy or too thick, but they're not - indeed, most of today's laptops feel incredibly thin and are much lighter than they look. Of course, making the switch to flash memory also means that you won't be able to upgrade your laptop's long-term storage without paying Apple for the privilege.
