Acer Aspire One Dual OS Netbook

When I first read that Acer is going to release an Android netbook I was happy that they did not abandon Linux in contrast to ASUS, only to learn a few days later that the netbook will be offered as a dual boot system with Android and Windows 7.
This was disappointing as it felt like a bluff package from a Linux user's perspective. I certainly do prefer a Linux only netbook or a netbook without a pre-installed operating system, so I still don't feel very comfortable with this offer.
There is at least one positive aspect though: regular Windows users who buy this netbook are much more likely to try a Linux based OS as it's already installed on their machines. They should see that Linux is capable of most of the stuff — if not all — they want to do with their netbook. While I don't think that this will boost Linux adoption, it may help with acceptance.
I am very interested to learn about your thoughts about the dual boot OS model. Do you think it is beneficial to Linux and whould you buy a dual boot netbook like this Acer Aspire One model?
