Lack of up to date internet s/ware means reliance on a PC for browsing. Once you've made the investment in PC hardware + OS, you may as well use the software, much of which is free (Flash, Acrobat, etc). As time goes on you use RISC OS less and less, and only for specific tasks. The time comes to upgrade the RO machine and the answer is clear: Virtual Acorn. So that's the end of RO hardware. To paraphrase Bill, "it's the browser, stupid".
