And the winner is--------Asio4all! 
 
OK,   I installed ASIO4all to this laptop I use at work and have been running Home Studio under WASAPI exclusive for a few months. 
So here you go, Asio4all wins the loopback test. It is very close to right on which boils down to you could use it for overdubing. 
I think the reason it works is it activates the offset controls and reports the latency properly. In all other modes there is no offset adjustment available. I am going to give it a run and see how it goes over the next few weeks. I noted what Sonar was reporting in each mode for latency. Most where all 10 ms which was what the buffer showed. Only Asio4all showed the RTL which was 30 ms. So there you go all you nay-sayers ( me sort of included) 
 

Hey Johnny, that sure is an interesting performance test.  
 
But I will add that I installed Platinum and most of my soft synths on my cheap Acer laptop with ASIO4ALL, and they run great.  I can stack em up until I run out of RAM (only 4GB) and they run fine.  But this laptop is really just a portable office, so I'm not trying to make a DAW out of it or anything.  I just wanted to see if I could play with my toys on it.
 
I must have gotten lucky with this laptop, because it passes LatencyMon with flying colors, even though it's only got a mobile dual core 4th gen i5 CPU and a slow 5400rpm HDD.

sounds like my lappy, though i have 8 gig of ram

I remember something like that.  That's either a lot of laptop users or people who still think an audio device is the least important feature of using a DAW.

laptop users i reckon

Well I own 4 audio interfaces,, having the option of just working on a laptop while away from home has always been a popular activity for even serious users. 
I'm a huge pusher of " The audio interface is the heart of a DAW system" anybody whining about audio issues will get that from me every time.  My favourite line was --- You paid $500 for a DAW and your using a $10 audio chip?  
I think a lot of the people attempting recording sans audio interface are struggling with money and using pirated versions. Anytime I see a new user and they are using X series I'll assume this. Those versions are all easily pirated. 
 
But if you find your self away from your main DAW with a laptop and are just working with midi files having on board certainly seems to be a good option. But I think there are laptops that this would not work as smoothly on. You do get lucky. 

Since the availability of this great WASAPI driver format I often don't turn on my studio system and run on my $10 onboard chip through my $15 desktop speakers. It's surprisingly OK for non critical listening. Also great for comparative listening.

same here, although using asio4all rather than wasaspi
