Actually, Apple spends remarkably little on R&D, perhaps even to a fault. The third chart on this page from Asymco [1] is interesting, especially considering Apple's R&D is for computers, phones, and whatever other lines they're developing, and the R&D for a company like HTC is likely to be clustered around its narrower product lines.
