This monitor needs it: Dell 3007WFP, 2560x1600.
The sound from my Asus P5Q is as interference-free as the sound from my Xonar DX. Again, rear ports only. I've heard interference on other on onboard sound and on cheaper add-on cards like the sound blaster pci, but not from this motherboard.
Not all motherboards are like this. Some have excellent shielding and the output (from the back ports, at least) is interference-free.
My last PC had terrible interference when I used the onboard sound, or so I thought. Everyone's advice was to get a sound card, and guess what? It improved nothing. The problem was the front panel audio ports, not the sound hardware. The back ports on the motherboard sounded just as good as the ports on the pricey sound card.
Since I don't game and I don't record audio, the only advantage the discrete sound card had was louder headphone output, and not even by much.
Instead of added horizontal resolution on an un-rotated monitor, you should be able to get added vertical resolution on a monitor rotated 90 degrees. I know there are X packages on Linux that do this.
And they only recently made 64-bit binaries the default when compiling with gcc. Before 10.6 you'd have to use gcc-4.2 explicitly, and specify -arch x86_64.
They said they were able to get to a "Connect to iTunes" screen (but no further), and that it was high resolution. Where is the screenshot?
The SD resolution you'll be restricted to is NOT 480i. It's 540p (960x540 in Widescreen). It's still better than DVD resolution (720x480 non-square pixels).
Is Apple going to allow VOIP over 3G? That would be big news. Currently I believe they allow VOIP over WiFi only, so the phone companies can continue to gouge you for voice calls on their network.
Normally making a call with GV would involve calling your GV number, and then dialing the number you wish to call (kind of like using a phone card). The GV webapp makes using GV less cumbersome.
But it sounds like you're wondering why someone would want to place an outgoing call through GV in the first place.
It uses your iPhone plan's minutes, but a local call to GV might be cheaper than a local call to another number, if you have a plan where you get to make a list of "friend" numbers with unlimited or cheap minutes (I think AT&T calls this an A-list). And as you said, it's much cheaper for long distance. Free between two US numbers, in fact (again, not including local minutes charges).
Also, you can blacklist phone numbers (known telemarketers, etc) from calling your google voice number, which for some reason the phone companies will never let you do with a regular number.
Cheap long distance, a portable phone number that you can forward to cell/home/work, and on some carriers, you can add google voice to your "circle of friends" numbers for cheaper/unlimited minutes.
The app is intended to make all of this as easy to use as the regular dialer/address book on the iPhone, rather than a cumbersome process as with a phone card.
