I actually bought the Aldi one partly because it was available to me. The store had only received 6 in stock so I was lucky to even get one.
I have 30 days to return it but so far it seems to be fine. Time will tell.
I bought the Aldi laptop too and I am pleased so far but I can't tell whether I'm getting the full Aero visual experience. It wasn't mentioned whether the graphics card supported it or not. Based on dotsman's comments I think it may not support the fancy Aero visuals.
