There is a software company out of Germany that sells an excellent office suite. SoftMaker (
http://www.softmaker.com/english/) makes SoftMaker Office 2012 which looks and feels like MS Office 2010 and imports MS Office files seamlessly. They supply it in Windows, Linux or Android versions for $79.95 to $99.95 and have reduced price promotions up to about 40% off sometimes during the year.. They also have Softmaker 2010, an MS Office 2007 clone, for Windows CE and Windows Mobile. At the present time there isn't a data base in the suite,but they say one is being developed to add into the suite later. I have never had any problem moving the individual version onto another hard drive or over to an upgraded computer. They also have a multi-license business use division. Another German company, Ashampoo, markets a slightly reduced featured version of SoftMaker 2012 for Windows at a reduced price. They also have frequent sales. I have created document files on one computer in with MS Office, moved the document over to another computer with SoftMaker, modified or added to it and moved it back to the MS Office computer seamlessly with no problems or inconveniences.
