Howday,
Recently have moved my dev. environment from Mac OS X to Ubuntu Linux. Ubuntu is really starting to shine as a desktop-replacement, dev-env. Anyhow, I use EA as a modeling tool often. I'm happy to report that it works out of the box with the latest Wine w/o all the convoluted steps and additional software packages you need to purchase -- listed on the EA guide to installing on linux.
There are some set-backs -- it is slower, and a little clunkier, but it seems to work fine. I didn't do anything special to get it to work.
I installed wine with apt-get. I ran the EA .exe installer. First time, all I saw was splash screen. After a reboot, I tried again, and the app came up, created a new model, made some new diagrams, saved it, etc. Have not exercised it much, but this is pretty cool news.
Hope it helps somebody!
Regards,
Davis
