What our customer's say!

"stick with excel 2003", I love excel and have run excel 2003 for years - but I sure don't like excel 2007 - the menus are busy, over-developed and non intuitive - and you can't modify them back to the "classic" look and feel - what a step backward - I'm throwing away the money I put into buying 2007 and getting 2003 back - it's a super program, but 2007 is a real step backwards interface and useability wise. Buy 2003 if you have the chance - it might be forced out sometime - then I go to a mac running XP and I'll stay non upgraded.

"When Will They Lower The Price?", Essentially, we were forced to purchase this upgrade to fix some problems with complex, macro-laden spreadsheets. It worked, but IMHO the price of this three-year-old software is too high. Every other similar product's price gets lower over time, but not Microsoft's products. I don't know why some other company doesn't copy their original formula, namely, creating similar software at a lower price that reads (and co-opts) the competiton's datafiles.
