> there is no thing such as small clients anymore

This is also right and wrong :-) Right regarding your perception, wrong regarding relative power. 1960s clients were small compared to today's small clients. However, 60s server were also small in relation to cloud servers. Today our small clients provide browsers and stuff like that but they aren't useful without servers. They can't run top-notch 3D games without high-end servers. The third wave of C/S will be in the area of A.I. with (small) clients which will possibly as powerful as today's cloud servers.
