A failed business model, (even Mr. Gates has jumped ship) of periodically taking a hatchet to last years still functional os model, in order to sell next years messy untimely birth of security holes and brokenness, thankfully will soon pass. Kubuntu baby!
Vista is actually a very secure O/S, when compared to XP which is a sub version of 2000. Using Kubuntu for designing, is like having a disability(and yes i have one).
