Good lord, this forum seems to have been infested with uber mac fanbois, not surprising for a mac forum but hey, worth a mention.
Well first of all the title is a little tired, sensational and contrived but the attention should surely be on the device itself. The HP IQ506 is a cool computer and I am seriously considering this as a kitchen computer myself.
I respect the comments of IJ Reilly seeing as he has something interesting to say on the subject but the majority of the comments on this subject have been poor attempts at witty remarks that come across as mac elitism. I think it's fair to say that everyone here fully understands that Mac OS X has not been ported to HP's line of computers and as kind as it is to inform us all of this, we really don't need this pointed out repeatedly.
This forum is fast becoming a place for mac users to laugh-off any attempts of the PC manufacturers to make something they would ever consider using, regardless of their merit. I notice that a large percentage are still talking about the old adage of the "long-term usability of touch screens", which is fair enough, provided that when Apple inevitably launches the touch imac, those that poo-poo'd the concept of the touch-screen do not herald the new mac version as 'the second coming'.
This HP does a lot of things that an iMac doesn't, such as offering a built in TV tuner, a good media centre in MS MC, a (relatively) good design, good looking software in the touchsmart software of which this is the second version and of course the multi-touch style touch-screen itself. Now that's not to say it is a better machine, if Apple launched a touch-screen iMac, I would choose that over this of course due to my own preference for OS X but thats not to say this is not a worthy opponent.
As IJ Reilly has already said, it's great that manufacturers keep trying to better the iMac as it gets some healthy competition going (not that that has ever really bothered Jobs & co, still not offering TV tuners in any of their products).
