This MS Office 2010 tutorial offers an overview of different editions so that you can make an informed choice while upgrading your software. As Microsoft is also offering free upgrade facility for users of Office 2007, this Office 2010 tutorial also explains how to get the Office 2010 without paying anything.
To begin with, Microsoft is offering Office 2010 as a free Office 2010 Starter Kit. This free Starter Kit includes free MS Word and free MS Excel with limited functionality. The facility is available only on new machines that come with Office 2010 Starter edition preinstalled. You can always get full functionality and add other Office software such as PowerPoint and Outlook by upgrading via Microsoft or any of its retail stores.
Before purchasing or downloading the trial version of Office 2010, check out the hardware requirements. If you are using Office 2007, you do not need anything in addition. The hardware requirements are same as that for Office 2007. If you are on 2007, you can easily upgrade to Office 2010. The minimum hardware requirements for Office 2010 are a) 500 MHz CPU; b) 256 MB RAM; c) 3 GB of Hard disk space; and d) Windows XP or later OS. Three GB of Hard Disk space is necessary for Professional Plus edition. For other versions, the Hard disk space can be lower. As you can see, the hardware requirements are really low, so you can install and use Office 2010 on most machines without having to upgrade the current hardware or software.
You can upgrade your beta version to full version of Microsoft Office 2010 at discounted rates. Besides the discounted upgrades, Microsoft is also offering free upgrades to some users of Office 2007. To qualify for a free upgrade to Office 2010, you should have purchased a valid copy of Office 2007 between March 5, 2010 and September 30, 2010. The free upgrades however, are being offered in the same "editions.” This means that if you are using a Student Edition, you will get the free upgrade to Student Edition only. For more information on upgrades, check out this Office 2010 article. It also covers the discounted upgrades for users who upgrade from Trial version to Full versions. These upgrades are in form of downloads. However, you can also go for a DVD version. In case you need the DVD, you will have to pay the shipping and handling charges.
In short, the new PCs henceforth will contain an optional Office 2010 starter pack that can be upgraded to full versions later using coupons that are available at Microsoft retail stores. The hardware requirements of the Office 2010 are so low that you can install it even on a five-year-old machine.
