Looking for Netbook Buying Advice

I’m looking to purchase a modestly equipped netbook for up to $300. I want the netbook to have a wireless card capable of promiscuous mode/packet injection. I would like it to have at least a third generation Intel chipset. I would like it to have a nice keyboard.

I’m thinking of either a Lenovo Thinkpad or Dell Lattitude series device. Any advice is much appreciated, thanks!

Netbooks are dead. By "netbook", I assume you mean a screen under 12 inches and a shitty atom CPU?

OI, atoms are great of you're mot an idiot about it.

For anything used I can only say look for a thinkpad T series or a dell D620/30.

By Netbook I just mean a laptop with a small screen, under "14.

I think that what you can find right now that resambles a netbook is a tablet with an Atom CPU and Windows. There are soo many ones with Atom 3537F and 2GB of ram that I don't know what model to direct you to. Maybe you can even get one with the new Atom CPU inside for 300$.
Even a Raspberry with a good wifi adapter is able to do such thing so, just go for the best bang for the buck thing you can find.
