I've been using OpenOffice.org Calc for a while now, but I recently decided to give KSpread a try after getting frustrated with Calc's slow load times. It rarely bothered me on my desktop system because I have 4GB of RAM and usually leave the program open, but my work laptop runs Windows XP, forcing me to run Kubuntu in a virtual machine. Unfortunately disk access is significantly slower and memory capacity is much smaller so the Calc startup time is painfully slow. KSpread is very fast, but are its other features good enough for me to stick with it?
