Well I did a few experiments. Tried the track pad = jerky movement. Plugged in my old Microsoft mouse and never had a problem. Very smooth. Trackpad just doesn't seem like it is working correctly. It just isn't reliable in terms of when it picks up my finger or not and jumps around. It wasn't a cheap keyboard ( $60) , but me dropping it a few times could have led to these problems.
Glad I asked if it was normal.
I took a chance on the on board graphics, but in general I think the computer is performing well.
