#10 seems like a good product, with exceptions. I have no problem with the update, I have a question that will be answered before I take the plunge. At this point no one seems to want to even approach this subject. Every body is so excited about the new 10, that it does not seem to be important. BUT, will it run MY software???????? If the upgrade forces me to buy new or spend money on expensive software, I will fight the upgrade. Is this one of the "costs of the 10?" I am running on 7 pro and have for several years. I use "Photoshop and AutoCAD" Both of which are quit expensive.
