Nvidia, Qualcom, TI, and most especially Motorola a strugling with the ARM processors. Just wait til Intel gets into the mix! The only one who is doing well is Apple. There isn't one large threat, nor one large front from the non-Apple ARM manufactures. -----
Erm... Nvidia, Qualcom, and TI are doing very well with their ARM SoC's.
The reason why you hear about ARM years in advance is due to the long development cycles in SoC design.
The story, over and over again with ARM processors is that they are high volume AND low margin. There is a lot of excitement around them, a lot of sales, a lot expectations, and time and time again disappointing profits. Qualcom is complaining about a downturn in sales, Motorola's new mobile division has gotten it's board nervous about the future and NVidea was supposed to hit a home run today with earnings only to walk to first base. I did love how some of the analysts were predicting that NVidea would pick up more discrete graphics card business in laptops. It's like they never heard of Sandy Bridge and Llano.
The problem with the ARM processors is that there isn't one large competitor who control the majority of the market. There are a few fairly good sized competitors who are battle scared from clashing with each other. I don't know exactly how Intel will approach this new market, but I sense that they will cherry pick some of the more profitable segments, trade on their name, advertise like crazy to build awareness and leave the low profit generic aspects to ARM where Motorola, NVidea, Qualcom, and TI will fight each other for market share.
