Microsoft is expected to bring out the next version of its operating system sometime in the 3rd quarter of this year. That said, there are a lot of expectations about what it will contain, how it will work, and whether it will live up to its hype as the biggest change in Microsoft’s family of OS’s since Windows NT more than 15 years ago. Indeed, the model is changing because of the new types of computers that have entered the market place, the mobile phone system, and the tablet PC system. They have changed the landscape considerably. In the middle of this is whether Windows 8 and Windows RT and the new touch-centric Metro interface will be available. So, the question is, which has the most promise?
These tablets and convertibles will run the full-blown Windows 8 operating system. So what do they have in store? The tablets come from device vendors such as Hewlett-Packard, Dell, and Acer and they will use Intel’s “Clover Trail” Atom processor. Some convertibles will also tap higher-performance Ivy Bridge processors. And, of course, chips from Advanced Micro Devices. Furthermore, the breadth of compatibility with existing Windows applications combined with the ability to use Metro mode or revert to a more traditional Windows interface to run older applications can help make this a solid product. Plus, Windows 8 Pro will be more corporate-enterprise friendly, including features like PC management, domain connectivity, and remote desktop operations. But there is an expected downside. Price. These devices are expected to be pricey, at least when compared to Windows RT devices.
Given the change in technology that Microsoft is pushing, it is no surprise that they would also use a different chip to run the operating system. So Windows 8 on ARM (WoA) — officially renamed to Windows RT by Microsoft — will run on processors coming from Qualcomm, Nvidia, and Texas Instruments. This is the first time a mainstream Windows operating system will be powered by chips from these ARM silicon suppliers in addition to those of Intel and AMD. Intel will run the others.
Is this good or bad? Well for the most part the good side will be price, battery life, and size. These devices will likely be inexpensive, have a good battery life feature, and be thin and light. And, it will come with Microsoft Office, whereas if you purchase the Windows 8, Intel based OS, you will have to purchase Office separately. More than that, consider that ARM will not runWindows 7, and older, stuff. So if you need to run any existing x86/64 software, then it will be best served with Windows 8 on x86/64.
All in all, you have two clear choices to consider. Take your pick
