I believe you are correct TJ. Since most laptops only have one port that can be used, which Windows reports as having 2 displays as you mentioned (integrated and external). This system allows for an extra display prior to docking - two external plus the internal.
I took the 3 without docking to mean there were 2 display ports on the side or back of the unit (plus the laptop display to make 3), and that the docking port would provide an additional 2 for five total.
I think the "3 displays without docking" is a feature for those of us (me included) that constantly take the laptop between home and office.. It is very very nice not to have to deal with display cables or docking station. I don't think it was intended to eliminate ALL wires (power) when at a desk with 3 monitors.
Ya gotta charge it at some point!
What isn't clear ..
- impact on performance of the displays when operating wirelessly.
- wireless displays that support it (most have resolution limitations of 1920x1080)
The all-day battery was a surprise to me as well. I didn't realize we had reached that capability in laptops. As someone who has spent the last 15 years, looking always for electrical outlets in airports, this is good news.
Chuck: I didn't come across any specific details on battery chemistry in covering this workstation nor did Dell play up any new developments which leads me to believe there is nothing really out of the ordinary here otherwise they would have highlighted it.
That said, here's a small bit from their release materials about what they're doing to achieve all-day battery life:
"An optional slice battery, ExpressCharge battery and NVIDIA Optimus™ technology, which intelligently and automatically optimizes the system to provide outstanding graphics performance when needed while extending battery life, are also available on both the M4700 and M6700."
TJ, the heat dissapation is becoming less and less of an issue as the components become more efficient. I recently saw another laptop (sans 3D) that had many of the features found in these Dell units. It seems to run cooler and runs all day. This is attributable to the Gen 3 peocessors and graphics chips. They use lots less power thanks to their funer line width lithography.
It is pretty crazy how much horsepower hardware makers (not just Dell) are packing into mobile workstation platforms. The heat dissappation question is a good one. I sit forever with a Macbook perched on my lap and I have to admit, it gets hot. And it's no near as powerful as this puppy!
Digital healthcare devices and wearable electronic products need to be thoroughly tested, lest they live short, ignominious lives, an expert will tell attendees at UBM’s upcoming Designers of Things conference in San Jose, Calif.
