Yeah, I think Dell still sends or offers the CD too.
Trying to deal with HP on repairs for a couple of customers' computers in the past year has quickly pointed me back to Dell again. Dell has their own problems, but the others seem to have so many more problems.
If a customer won't buy a computer from me, I'll cautiously recommend a Dell.
HP, Dell, and Apple are the top three sellers now for a reason. Sure you can buy cheaper but you normally get what you pay for. Depending on your purpose you might try buying a media kit from CDW for ~$30, but your OEM license key from Acer would cause some issues with full reinstalls etc.
