Well first its impossible for all sites to be non discriminatory against the disabled,totaly impossible - for example,and heres 1 example how would or could Youtube.com work for those that are blind ? i would love to know ?
Also whilst technicaly you are right about the web moving forward you still discriminate against those in poor countries - you assume everyone can afford vista or xp service pack 2 ? in reality half the world is still using windows 98 and a lot still on dial up modem.
Yes tables might be an older way of creating websites but for a lot its better,and after all if it works - dont fix it -
I heard the other day that unleaded petrol is old school,
the way forward is bio-fuel,pop it in yer supra
