MacBook Air :: It Constantly Freezing Up

The MacBook Air that I purchased a month ago, freezes up on me constantly. I've researched various forums, and some are stating that this could be due to the system overheating. I really do not believe this is the case with my MacBook Air, as I rarely use it. I only use it for traveling (I write for a living) and every time I use it, it freezes. It is not hot when it freezes.

I could be working on a document or just browsing the Internet and all of a sudden, the cursor and track pad stop working. Sometimes it's ok and when done, I close the lid, or put it in sleep mode. However, when I return to open the system, my track pad, cursor, everything freezes again! I literally have to shut it down with the power key (not even the apple/quit keys work) and reboot the system. Another flaw is that the darn thing will reboot, but I cannot log it (mouse / cursor still don't work). Therefore, it takes bout 4 reboots to engage it again. 

I'm at my wits end. I've had this thing to the Apple Store twice and they always say "I've never heard of this happening" and after extensive troubleshooting, I walk away without any resolution. To say that they have never heard of this issue is astounding to me, because the more I research this issue on the Internet, I'm finding more and more complaints. I will also say that this is my SECOND MacAir in one month. I had the same issue with the first one I purchased (after only one week), and returned it to BestBuy for a brand new replacement. I thought it was a fluke. Guess again ... same issue with this one.After all these years, I decided to take the plunge and get an Apple, but I must admit, I feel completely burned. $1200.00 for a laptop and I can barely use it. I'm sick over the entire thing. I will never buy another Apple again.
