Whoa, that was like a quoting BS from some HDMI consortium sales manager. First of all, HDM signal, even while digital, is *much* more prone to interference, due to strict timing requiments and high bandwidth transferred + dropping signal entirelly, in case of errors. It results in much shorter acceptable cable length (without active signal boosters), and/or ugly fat cables.

In my real-life case, just placing N900 on standing leg of my monitor (~5 cm from HDMI cable), listening to FM radio *and* getting a call results in ~3 seconds of black screen. Never happens with VGA.

Also, HDMI is *not* royalty-free:

An alternative fee for HDMI manufacturers making less than 10,000 units per year is an annual fee of $5,000 with a royalty rate of $1 per unit. The royalty only applies to final products and does not apply to products that are included in, or with, a licensed HDMI product that is already subject to the royalty.[132] An example is that an HDMI cable sold directly to consumers is paid for by the cable manufacturer but if the cable manufacturer sells the HDMI cable to a HDTV manufacturer that includes it with an HDTV subject to the royalty then the HDTV manufacturer pays only the royalty on the HDTV.
In comparision, DisplayPort is semi-royalty-free - you can include it in your product for free, but some parts of specification are free *only* for consortium members.

This is academic problem, though, as we need neither. As stated in my previous post, VGA adds missing piece, that allows us to get practical results of *both* HDMI and DisplayPort (minus things really not needed by anyone, like digital rights management through HDCP), with only one drawback of using more cables (or cleverly made custom cable). I don't know for you, but I can perfectly live with that.

BTW, analog video is not going to phase-out, at all! They're just planning to slowly replace physical connector, but you will be perfectly able to connect your VGA output to DisplayPort input of your monitor/TV (in case VGA input lacking, which I seriously doubt to happen anytime soon, BTW), using semi-active (powered through cable, from monitor/TV), lossless adaptor.
