IBM doesn't make PCs anymore, they sold their laptops and desktop PC division to Lenovo in 2005. So, it's been 9 years that IBM has NOT been selling Laptops and Desktop PCs.
----------
Do you not read? It's just a deal so IBM can sell iPhones and iPads. That's ALL the deal is about.
When IBM goes to an existing client or a future client about a project, they are the top project manager, if you will, for the ENTIRE project, so they will bring into the deal whatever hardware, software, custom software, project management and other services that are necessary to complete the project. Apple doesn't do project work. What they do is sell hardware and some software and that's it.
IBM has many software companies that they've been purchasing over the years, plus they partner with other major software companies, they also sell higher end servers, mainframes, super computers, they have administrative personnel, software developers, the retail cash register systems, etc. etc. So, what IBM is doing is more projects where mobile devices are part of the project, so they are partnering with Apple, so they will be selling a solution based on iOS devices and probably not focusing much or at all on other mobile devices, unless they sign a deal with Samsung or another company that sells a competing product. Could they still do project work with Windows tablets? I don't see why not, but they don't sell those anymore. They sold off that business, so the customer would just buy that hardware directly from HP, Dell, Lenovo, etc. if they wanted a competing product.
Is this good for Apple? Sure, it helps drive more mobile devices into the Enterprise where Apple wouldn't be as successful because they now have a big systems integrator, project leader driving that business.
The problem Apple has always had is getting into the doors of large Enterprise accounts. Sometimes, they get in the door, but they can't keep the door open because they have other large companies like HP, Dell, Microsoft, IBM, etc. driving business away from Apple because they don't do much integration with Apple. That's what the problem with Apple in the Enterprise is. So having IBM is going to help drive more Enterprise business that will hopefully be long term business and maybe EVENTUALLY drive more OS X business. Maybe IBM will eventually add OS X computers to the deal, which they can do at any time, but for now, it's just iPhones and iPads.
