I'm a tech guy as well, although more on the hardware side (I'm an IC designer). You are correct in that Intel isn't going away anytime soon. They have a stable business and are clearly the market leader by quite a long way when it comes to desktop PCs, workstations, servers, etc. But where will the future growth come from? If you want a growth story starting from a smaller base and representing more of where we are going you have to take a hard look at ARMH. ARM has a great business in the mobile processor space and also a long held deeply entrenched position in the IP business (embedded processors / standard cell libraries / as well as various other IP) so that it isn't going away any sooner than Intel will, yet its embedded processor business will almost certainly grow faster than any business Intel is in. I haven't done any research into these companies recently as far as the stocks go so I won't speak to their current valuations, but I think as far as where the technology is headed ARM is in a much better position to take advantage of current and near-term trends.
Also one word of advice on circle of competence. You can (and probably should) work on building a circle of competence for investing purposes in a number of areas outside of technology and I highly recommend you do so. As a recent college grad in the mid-90s I used to invest exclusively in tech stocks, because I believed that I should stick to what I know best. Needless to say I got hit pretty hard by the tech crash of 2000 and have been working on extending my circle of competence into other areas for investing purposes ever since. I have been investing in restaurants, restaurant equipment companies, insurance companies, construction/farm equipment companies, and with ISRG, a surgical device manufacturer. The only tech stock I now own is GOOG and restricted stock in the semiconductor company that I work for. I'd highly recommend picking an industry that interests you outside of technology and start doing some research and trying to build some competence in that area. It can never hurt to widen your circle, especially when your initial circle of competence only includes one industry which is very difficult to invest successfully in.
