BTW, im a Mainframe borned System Programmer, so every pc platform looks "weak" for me
Why is that actually? Years ago my dad was project leader for various programs that were being developed to run on mainframes. Hehe, those programmers actually actually had to write their code on paper, then some typist typed it on a machine that made those cards with holes in it ("pons kaart" in dutch, don't know the english). The mainframe they used had a massive amount of 200KB RAM . I think they are now mostly swichting from AS400 to Bull or something like that. My dad says a mainframe is much more reliable than a pc.
What are other main differences that make you say a pc is weak?
