    Pity. But I can live with that I guess ;-)

    Appending "especially when..." to a statement means the statement is true also without the appendix, and *even more so* with the appendix. Your statement however is false without the appendix, so what you probably meant to say (I can't be sure though) is "as long as" instead of "especially when".

    Yes, and we can even quantify it exactly: regarding ARMv7, there're exactly 3 companies that do their own core(s) from scratch instead just licensing them from ARM Ltd. These are Marvell (Sheeva PJ4/PJ4B), Qualcomm (Scorpion, Krait) and Apple (A6 core).
    Btw, I don't think "reference design" is an apt term for what is happening here. It's not like ARM ISA licensees take a core design from ARM Ltd. and try to enhance it or adapt it for their needs. In fact, they develop their own microarchitecture from scratch with the ARM ISA as specification which the microarchitecture is an implementation of. This is in contrast to the ARM core licensees who take and use cores from ARM Ltd. as is.
