I got my n810 recently and I love it but I really need an alternative to OpenOffice for loading .xls and .doc files. OpenOffice is painfully slow, to the point that it is just unuseable. I really only need .xls for a company mileage tracking template. There are empty fields in this .xls for beginning location (which you type in), beginning location odometer reading, destination, destination, destination odometer reading, and then it adds up the odometer readings. There is a separate section for each day, and then it ads up the totals for each day, and at the end of the page, ads the totals up for the whole week. If there is an alternative to OpenOffice that isn't deadly slow (maybe a mileage tracking application), please let me know!
