To all the people saying that the Smart XX OS updates are mostly for bug fixing, you're wrong. If you check the changelog, you see that yes there is a bug fix in every release, but there are also like five or six nice features added that the customers requested on their website. No, we don't care about having to update our OS. Hell, if they came out with a new update everyday I wouldn't care because the SmartXX has the option to flash the chip over a network. This means all I have to do is type my box's ip into IE and slect the update. Done. So it all depends on your style. If you want not as many features, but an easier install and the easire (though more expensive) LCD option, etc. get a Xenium. However, if you want a more advanced chip that has more flash space (yes there are uses for it esp. with ED @ Chip which takes up 2 MB), easier BIOS flashing, better software (including more updates which ARE A GOOD THING) then get the Smart XX. The choice is up to you as both chips are good and have their individual strengths and weaknesses.
