I have a mac, which is great 99% of the time. But I can't use EQ because they don't seem to like macs (ie they're lazy and don't want to hire programmers to make a unix based system that fits into the OSX kernals). From the last sentence you can see that I'm a little bit of a geek, and I won't deny that which is why I'm super excited for what the people over at Threadbias are up to.
I saw this over on Freshly Pieced, there's a Kickstarter campaign for a WEB BASED quilt designing tool. That means it doesn't matter what kind of computer you have, all that matters is that you can get onto the interwebs. If you have interest, please consider donating to this group.
