It's pretty much unanimously agreed that the design of Dell's M1530 and M1330 is leagues ahead of its older bland-box styling. Of course those are consumer systems which is why it's good to hear that that the same kind of aesthetics are set to be available on the business orientated Latitide range of systems bringing them in line with the non-business world. Never a bad thing you'll doubtless agree.
The systems in question are, according to Engadget from whence this leak comes, labelled the E-Series and they seem to be carrying the same brushed metal look that is all the rage right now. Specs wise we're expected to see 12in, 13.3in, 14.1in and 15.4in models with LED backlit panels and varying resolution options. Weight for the 14.1in and 15.4in is slated at around 1.9Kg and 2.3Kg respectively.
Apparently we should also see a DisplayPort connector which will be a first, although an unsurprising one given Dell's backing of the connector. Other known features include PC Card and ExpressCard slots, eSATA and a slew of USB ports. Also expect such features as a built-in optical drive and Ethernet port, even if they aren't required on a laptop any more according to Apple - and no this running joke is never going to get old.
That's about it on known details for now, as is the nature of such leaks, so we'll have to keep a look out for some official word form Dell. Knowing the company's track record that will be about a week before the actual launch, so don't expect anything any time soon. So hurry up Dell and do the honourable thing.
