My FW800 Lacie is faster but I prefer portable drives for size and noise output.
My next Mac will have FW800 and i'll use it for most of my drive needs. I'm trying to consolidate my storage into a Drobo or something like it. The new Drobo FS sounds interesting but it's expensive. I'm still waiting for Apple to enter the Home Server market before outlaying a bunch of cash on a storage device.

You're not focused on the core of either technology. "A lot of people" does not constitute anything more than a niche within a niche.
HDMI is for consumer HD devices that hook up to HDTV display. It's bit depth and refresh rates are tailored for the playback of digital video and audio content
DisplayPort is a planned successor to Analog VGA and DVI. It's tailored for running computer displays and supports higher refresh rates.
In 5 years when 4k monitors are available from multiple vendors. HDMI will be suitable for playing back video content and DisplayPort will be suitable for running 4k monitors for content creation.
There's a reason why a Macbook has DisplayPort and an AppleTV has HDMI. Apple knows how to put the appropriate connector on the proper device. They also understand where the market is heading and what display technology is coming.
I fully realize that HDMI is usefull. Hell even I got giddy the first time I hooked up my HD player to my HDTV with one HDMI cable. However today I'm anxiously awaiting a refresh to the Apple TV. I don't see any reason that why I should hook up "any" cable to playback audio or video on my AV setup.
TV will soon go Wifi on a lot of models and accept music and video content streamed from networked PC/Mac/Mobile devices. If you're still plugging in devices to access content you've failed.
