Ah, I have had both in the last 2.5 weeks and let me tell you, if you are mainly using it as a desktop replacement, you want the 17'' LCD. Trust me, once you put it on your desk, you will fall in love and wont go back.
I had the M70 for 3 days, 2.5 weeks ago and ended up having to exchange it 3 times. Finally, I got a sweet deal on the M60 for literally the same price, and since I always wanted a bigger screen i went for it. Havent looked back since.
However, it is not perfect. Yes, the keyboard like many users have said, the keys are really stiff...but im sure over time it will break in, like all keyboards will. But when i type on my brothers A70, the difference is like night and day. I dont know why the M60 keyboard is made so snappy? Odd, but not a big deal. Definitely need some epsom salt to loosen up the hand muscles, its like getting a workout, since it IS typewriter keys!
The biggest grip I have with the keyboard is how two of the most commonly used keys - the period and the right shift, are shrunken, and yet the left shift is 4 times the size? That just doesnt make any sense to me. What Toshiba should have done was shrunken the numpad, because though I love mine...how often do you use it really? Not nearly as much as the right shift. Through the 2 weeks, I have yet to get used to this. The period key is fine, but finding the right shift is bit tricky. But then again, I use a standard full size keyboard at work, typing away at it for 8hrs a day anyways.
Surprisingly its made pretty well. Hinge doesnt creak when I open it, the keyboard doesnt really flex, but I think this has a large part to due with the super stiff keys.
Although it would be of great help while typing, so I'll try that.
