Re: The difference
I have Inkscape installed on both my OpenSuse boxes and a Windows 7 box and I'm not hugely impressed. I have to say I prefer the way it works to that of LibreOffice Draw, but I have found it to be somewhat unstable and not a little sluggish in use. Xara (I started with Extreme 6 and now use Designer Pro X10) "just works" most of the time, though only under Windows of course. I still can't get used to the traditional "windows within a window" approach of non Risc-OS applications though. Terribly wasteful of screen real-estate, particularly as I have (at work) three variously-sized screens, and it reminds me of Windows 3.1's "Program Manager".
