I think I know the answer (no) but just want to make sure. I have a family account, which expires in August I believe. Was at Compusa today and they had them 50% off, so I picked one up for $90 to use when I need to renew. Thing is, its the MA362Z/A 4.0 version, and I know they are now on 5.0 with a differnet sku. This one will still be usable to renew when its time (I hope) or did I just waste $90?
