My 3 year old budget laptop has a 1280*800 screen
current laptops in the same price range are 1366*768

Those are the 'wide screen' adaptations of older standard sizes that are being pushed now.
You might not mind, or even think it's great if you watch movies all the time on your laptop, but that's not what I do with one.

There's a second and very important limitation: Signal to Noise Ratio. Noise has a physical minimum, so to increase SNR more power is needed.

This.

See Shannon's Law: http://en.wikipedia.org/wiki/Shannon%E2%80%93Hartley_theorem

Shannon's Law contains nothing about current limits in technology.

Basically, for a given Signal to Noise ratio at the receiver (specifically at the detector), when the noise power approaches the power of the smallest bit division, you cannot reliably recover those bits and further subdivision is pointless.

Even in a lab, Signal to Noise is never infinite, and put a finite limit on the number of bits you can send in a channel. In the real world, the Signal to Noise at the receiver only gets worse the greater the distance between the transmitter and the receiver (inverse square), and this excludes other sources of 'noise' such as interference from other signals, multipath, propagation or other degradation effects such as holding your iPhone incorrectly.

Comcast claims that a good network maintains a 1:1 with them, but that's simply not possible unless you had Comcast and another broadband access network talking to each other. In the attached graphs you can see the ratio is more along the lines of 5:1, which Comcast was complaining about with Level (3). The reality is that the ratio argument is bogus. Broadband access networks are naturally pull-heavy and it's being used as an excuse to call foul of Level (3) and other content heavy networks. But this shoulnd't surprise anyone, the ratio argument has been used for over a decade by many of the large telephone companies as an excuse to deny peering requests.

I'm suprised the ratio is that good considering most broadband service providers force their customers into highly asymetric connections (8:1?, 10:1?, higher?) and not allow them to run servers. It's disingenious to expect the Level 3 to be a 'good network' and maintain a 1:1 ratio with them while they force their customers into a highly asymmetric traffic pattern. It appears to me that it's in the ISP's financial interest to force high assymetry.
If Comcast want's Level 3 to pay up for traffic ratios higher than 5:1, and Comcast forces their customers into still higher ratios, shouldn't Comcast be paying (refunding) their customers for the 'excess' traffic?
