Laptop Specs - comparison

This is a comparison between the Dell I've ordered (but will cancel, if it seriously is only going to be arriving in August) and the Acer I'd probably have to end up getting instead :-( Note the difference in weight and battery life ... oddly enough, the Acer is worse for both (I could understand heavier battery = more battery life, but not heaver and LESS battery life!)

I suspect that their system is just really bad at estimating delivery dates, though - or maybe the order and delivery dates are in different formats (d/m/y vs m/d/y) - because yesterday it was in pre-production, waiting for parts, but today it's in production, which means it's being assembled. Then it just needs to be tested and shipped, and I don't see that that can take 2 months!

Update - as of today, the status is back to pre-production! How does that work?! I think their online order status tracker is well and truly not working :-(
