I've been following Buffett since the 1990s and his reputation for shunning tech seems to be based on his wise choice not to play in tech in the late 1990s. This seems to be based on relatively simple valuation techniques as well as asking the important question "Do I understand the business?". Of course he missed some winners as a result of this but overall it helped his results. His two tech moves so far, IBM and Apple, don't violate that approach at all so it makes sense.
