It is my understanding that when Lion is available, it will downloaded from the App Store. If I understand correctly that means I will not have a disc as I do with Snow Leopard. I am a noob who bought my first computer about 8 months ago. I have had to do an OS restore on three occasions (under the instruction of Applecare tech support) and that required the use of the disc supplied with the computer (Macbook 13"). The restore solved my problems. If Lion is downloaded from the App store, how would one do an OS restore without a disc? Sorry if this is a dumb question - but you all are the only ones I can think of to answer my question. Thank you for your help.
