I would love to use numbers so to take advantage of iCloud as well as maximizing the look on my ipad when I use that to show spreadsheets. The problem is that my sheets are large with a lot of calculations and numbers runs incredibly slow. almost 5 seconds just to click on a square. I have a 17" macbook pro 2.3 gz i7 quad core, 512 sad and 8 gb of ram. is it my computer or is pages just very slow compared to excel?
