Yeah I have an Acer with a ULV and a 6-cell and get over 8 hours. I don't know what Dell's problem is.
Maybe Dell uses lower mAh batteries? Number of cells is only part of the story. Anyways, no way they could fit ginormous batteries into that slim profile.
IMHO, the only laptop worth having is a Apple one... I've looked high and low.
Uh, no.
The one thing I have to say about Apple notebooks is that I like the AC adapter connection. Seriously it isn't rocket science. My hot drinking water heater and my deep fryer both have the magnetic plugs on them. Why don't more notebook makers use them? Then again, wonder how many people have re-purchased HP notebooks due to the AC adapter socket breaking out of warranty...
I got my L13 today, it is a styling laptop. I'm looking forward to getting to give it a thorough test run.
You got it one day before I got mine. Just got it a bit ago and it is charging as I type.
It's about a 4 hour machine under light web browsing use with the screen at about 75%. Probably somewhere in the 5 hour region without the wifi on and doing Word stuff.
Is that actual battery life on yours? If so, I could totally live with that.
Here's my impressions of unboxing and handling it (haven't powered it up yet). The packaging was "meh." Basically the notebook sat on the bottom of the box and was held in place, so there was only a couple layers of cardboard for padding.
Looks new. Minuscule blemish on bottom and a honking huge green "refurbished" sticker on bottom. Seems to be same weight as my Hannspree (3.4 pounds). Hinges pick up fingerprints. Why, Dell, why? Matte screen, matte plastic and matte aluminum abounds (or is that magnesium?). Hooray! The glossy EVERYTHING of the Hannspree was getting old. Bit of flex, but actually feels less flexy than the smaller Hannspree. VERY thin!
Why couldn't they have put an HDMI-out and a few more USB ports on it? I know "business" notebooks need VGA for output to projectors, but c'mon! Touchpad is nice and large with nice buttons. The whole notebook has a look/feel of quality to it. Keyboard has a reasonable feel - I predict it will type nice. eSATA is a nice option and looks to be combo'd with USB, so I guess there's a second USB after all.
Wow, even comes with an OS reinstall disc and USB mouse. The included optical drive was a surprise. I knew it came with one, but two things stood out. First is that you have to install the bare slim ODD into the external enclosure yourself. Second is that the external enclosure is eSATA. Wow again!
How the heck does one take it apart? I'm seriously wanting to bump the RAM to 4GB and swap out the 160GB 5400RPM HDD to an SSD. Love that it has Bluetooth and Wireless N meaning fewer stuff to upgrade/dongle whether or not I use them.
The big disappointment is the AC adapter. Seriously, it looks like the same 65W brick I had with my first notebook ever (a Dell Latitude D800? had original Pentium M 1.3GHz). A nice slim notebook like this and... and antiquated brick? Does this even need 65W? Also, the brick for my Hannspree is of similar wattage and is barely bigger than the 40W that came with my MSI netbook.
If I can regularly get at least 3 hours of battery life for web browsing, then I'll be content with it. If I can software tweak it for 4+ hours, then I may even stop window shopping other notebooks.

Been looking at that Asus UL30Vt on Amazon for $630. Much more than the $450 I paid for this Latitude, but the Asus has claimed 11 hour battery (8-cell plus can keep CPU at low speed) and has overclocking and a switchable Nvidia 210 GPU in a 3.75 pound package with aluminum lid. I have yet to see comparable Core i3/i5/i7-um notebooks with that battery life/weight/graphics/price.
