I've had good luck with my Latitude 13, but TBH I don't use it all that much. I much prefer using my overclocked Core i7 with 30" monitor when I'm at home. 😛 I'm using the Latitude 13 right now because I've been traveling. That's really my only use for it.
I got mine as a Dell Outlet refurb (big green sticker on bottom that says so) with 25% off coupon, making it $450 shipped price. Besides the SU7300 CPU, it came with 2GB RAM and 160GB HDD. I swapped out the HDD for an SSD. The Latitude doesn't come with a webcam, which is kind of odd because I'm more used to consumer notebooks which all have them.
The only issues I've had are a stripped screw hole and slightly warped lid. It came that way, but again, it was a refurb. On this trip I just noticed that the lid almost doesn't lay flat. It might be just a side effect of the slightly warped lid.
LIKE
Metal exterior
Almost zero glossy surfaces
Matte LCD
Keyboard is full size and has a GREAT feel, plus keys all in "proper" places.
Touchpad is suitably large compared to smaller notebooks (like 12.1" or 11.6" models)
Service manual available on Dell's site for disassembly
Slim profile
13.3" form factor seems a really good compromise between being really portable and being really usable
Came with powered eSATA external slim DVD drive
HATE
Sharp edges, especially front corners
Lack of properly fitting sleeves
Short battery life (just over 3.5 hours, my netbook and other CULV both get much more)
MEH
Single SODIMM slot so no dual channel
Seems heavy for something so thin
Fresh install of Windows and there's a mystery unknown device in Device Manager
Touchpad doesn't seem to support multi-touch
Still feels laggy on occasion in normal usage
Unsure if Bluetooth is present or operational, maybe that's the mystery device?
Single speaker seems tinny even compared to my netbook
If I count each time I've used this notebook as a "day" then I probably have less than 3 weeks of use out of it so far.
My hope is that someone comes along and really loves it, so I can sell it and pay the difference to go up to a Vostro V130. 😀 Even the base $430 model should have slightly more performance on the CPU while being significantly better (though still not that great) with the integrated graphics. I played some multiplayer Flatout 2 this past weekend with a couple buddies and... it was laggy with everything turned down as low as it can go. Supposedly the IGP of the Arrandale is roughly 2x the performance of the GMA 4500 HD that is part of the GS45 or whatever chipset these older Dells have. I know these aren't "gaming" notebooks, but would be nice to be able to crank up some games newer than the original Starcraft. 😛
