I use both but predominantly Exel at work as I am an accountant and Word at home as writing is my hobby. I can remember in the eighties it was Lotus 123 that had the market and not Excel. It was almost mandatory to have Lotus knowledge to get an accounting job. It's interesting how such strong market share can be so completely lost.
No, I use open office. I got tired of having to relearn the menus when they changed them as each new version of Word came out. With Open Office Writer I can just use the same program I'm used to and save it as a Word document. I had to learn to use Excel at uni. I'm not great at it but I can do it.
I use both extensively on a daily basis. But I am not very good with excel rules and tricks. There is SO much we can do in excel and I always end up learning something new when I turn to my husband for help.
I use word. I use excel. Trouble with Excel is you need to use it often to remember it. The same was when I was at work. I did use Excel but only for entering data that was required by someone else. I think Excel is good for managers who know what they want (result wise) -they should use it but most people I know that are Managers don't know how to use it but they have people at their disposal that actually know how to use it but it is the transfer of requirements that creates a problem. It is one of those systems that Managers should know personally IMO. So many arguments witnessed when I was at work.
I used Excel for family tree layout and I thought it was easy, it was great. Everyone accessing my good work said that the spreadsheet were rubbish when they accessed it (or tried). What do other people think.
