I recently added a dual core cpu and a better graphics card to my computer and took the opportunity to buy an oem version of vista home premium. I now have a duel boot system. Vista is pretty but much slower than xp. I like the sidebar in vista but now I have got a similar sidebar in xp. I am finding it difficult to find any benefit of vista over xp so did I waste my money? Can anyone tell me how vista is better than xp?
