In my opinion the EOS-M is not worthy of its price tag due to its poor AF, even at $299. Opinions vary. And people can buy in to first generation gear; it's their money - their choice. They know the risks going in. And when there's a fire sale, it's pretty telling that the new technology (ie, dual-pixel AF) just made the previous generation obsolete.
You are spot on. I picked up my M last night and realised that it didn't have dual pixel AF. I cried. I gave it a viking burial. I think my 7D and 600D are going to get it next.
Obsolete is in the dictionary. Look it up.
Are you being cute? I can't tell.
Obsolete: Out of date. No longer current.
The dual-pixel AF system launched on the 70D single-handedly restructured Canon's line that is based around Live-View focusing. And, in case you are unaware, the EOS-M line is the only one based around Live-View focusing.
Do you really not find it curious that there's a $299 fire sale on the EOS-M, and then hours later rumors drop of a replacement in the works?
You may want to look up naive... it's in the dictionary too.
