I was lucky enough to attend the fair this weekend. It was a great experience (it wasn't just Amiga related). The A1-X1000 (please, that's a dreaful name, it needs to be shorter) looked a nice system. I managed to crash it by attempting to load 2 copies of Blender (sorry guys, but I did have a chuckle about this!).
I came away impressed, but clearly there's a lot of work still to be done. The graphics subsystem may be fairly complete, but it's dreadfully slow in both desktop and 3D operation (Quake 3 at 4fps). I'm also left wondering what market there is for this type of system. I'm really struggling to think what a PC can't do (at half the price) that the X1000 can do. The Xena chip may be a shining jewel amidst an otherwise dusty relic, but it needs a massive marketing push, developer tools and solid showcase examples.
There may be a niche within music production or video editing which the Xena can be used for - but I'm again struggling to see why people wouldn't go with a Windows machine. I'm no Windows fanboy, but at least it's got good support.
Oh, I *will* be buying an X1000. I am, after all, an ex-Amiga owner wanting to re-live my youth...
