I have promulgated the same message for some time now. You really need to go into a live business, be it a contact centre, warehouse, or estate agents. You will see swiftly that there really is no return on investment in Vista, thus no compelling reason for the costly upgrade.
I am saddened by the inability of people to see this rather simple deduction. If you missed my opinion on the matter, look at this
thread. Home users are sold Vista because they don't know any better, and it's not so bad. £500 will get you a far better PC today with Vista and probably at least 2 Gig ram. In the XP days, you'd have been stuck with 256MB.
People are not stupid, and are better educated now. PaoloM and crew need to procure some compelling features and advancements. As it is I don't quite see what the problem is. Intel have not ditched XP and gone over to Linux, it's a case of we still like XP. If I'm a manufacturer and people prefer an older version so what? I always buy Heinz baked beans, but I may try some of their other combinations, but the classic Heinz will always suffice.
If people like XP, keep developing the product, and adding value to it. Update it to include new fonts, more secure kernel etc, whats the problem with that?
