I have. And the "majority" mentality is reasons why I haven't seen such a device UNTIL NOW or much offerings of those options. I looked at any and other solutions (note solutions, not a single device or piece of software) and most aren't satisfactory until now. Given the "majority" catering - it most likely continue that path.
You mentioned I should not apply my examples and other perceived examples, but that is the most concrete ones I can give. Elsewhere, arguments are determined by solely business numbers, market share numbers. Things that is just a metric that can go nowhere - something that one is quickly to look at too.
Over a decade. AMD and now mostly Intel is making strides. Elsewhere, many are re-inventing the wheel that doesn't apply well enough for the sake of standards changing - or even catering to working standards. I seen this with Steam and Gabe's perceived direction with the Steam box, when in likely, a straight forward streaming box (which they ARE releasing now, a good thing) or a simple move of the PC and desk setup, or setting a Miracast transmitter/receiver or WiDi transmitter and receiver (again, not ideal given the EM environment of some households, but if streaming can be applied, a hard ethernet line can simply applied in a same manner for fuller robustness - but no one would think of this.
Soap box for long. Didn't mean to take the thread off topic.
On topic again -
I handled the Surface Pro 3. VERY LIGHT for what it has inside on similar to same as the Surface Pro 2 chip wise (despite the larger screen area). I do not agree with the pen implementation. Pen disgreemens are more or less the lack of an eraser end and the radial menu of Wacom - one of which can be resolved driver/software end, the other will require a second pen version release (much like different keyboard covers for different purposes (power cover for one).
The 3:2 aspect would be again, very nice for areas of work. Right now, with my Pro 2 - I have space horizontally that aren't in the center of my pen for working and needs panning - at the same time, that space can be filled with layers panes or a snapped app, but that more or less is a workspace layout preference - both aspect ratios aren't bad at all and can be workable.
Fuller typing and simultaneous text and content, can be better with the 12 inch screen. It is no 14" laptop, but for the overall area, I would appreciate it for typing and referencing alongside notes. The larger resolution would be in line with more compact laptops. I can see programming lightly well on the device while referencing. Multiple tabs can be pulled in a same manner, and with a pen in hand, I can make off notes elsewhere in a switched task, and quickly set down to continue typing.
The new power connector is very nice - It goes on more quickly than the previous connectors. More than likely, with the extra contacts, it would be a sole connector for docking (as possibly Microsoft has intended).
Not sure about the extra strip for "solid" keyboard typing. I have no problems typing on the type covers of past, in various orientations. I do have to adjust for the Start bezel icon - Charms options would possibly disable it through the Settings option and easily be able to add in - and be beneficial to other WIndows devices with a Start bezel icon.
Pressure works well. The pen tip comes much closer to the screen. There is a certain tilt where it would go off alignment to actual cursor position though. Edge screen drift is minimized compared to the Wacom implementations. And if out in the field, there isn't the EM of the digitizer that may add to the EM "noise" that may distrupt wireless communications, since the EM of the digitizer is isolated in the pen, and active upon using the pen.
Due to the closeness of the cursor to the pen tip, there isn't much need to cursor hover, but cursor hovering with the pen is still viable - with a slight delay, that is very tiny to show the cursor after the pen is in proximity.
Palm blocking works well still. Much better than before with the Pro 1.
Again, much like the Pro 1, I await driver resolvement - but unlike the Pro 1, I am not out in a rush to buy the Pro 3 as I already have my solutions at hand. Computing wise, software compatibility wise, performance wise, everything is comparable. the forms improved however. Certain functions software pending, aren't there - but it is something I experienced on the Pro 1's growing pains.
Gaming, I expect the device again to be a bonus in leveraging PC games of the past and present. The performance isn't too much of a difference unless going to an i7 setup which is a slight improvement. Nice on the go - but if one is to really and solely emphasize gaming, there are better performing mobile devices for PC gaming out there, just as dedicated touch devices for simple games (though Modern areas can leverage those very same simple touch games).
Also, the Pro 3, I would anticipate lasting me for a few to several years. Hardware has gotten good to where longevity is much more than the past Athlon-Athlon XP upgrade increments - pending other aspects of the build holding out and battery integrity. Price is in reason for the life expectancy if not more so.
The pen loop in the keyboard is a nice slight addition. I would use it, given it being there. I like the thickness of the pen, it is better to hold for writing and character work with off characters. Again, I do not entirely agree with the sole button to turn on the device, as it isn't much to turn on the device as is now, but I would like to see a second pen having a much expanded erasing end / right click end possibly.
Final notes are on the laptop handling, one of which is the kickstand, now completely variable to an extreme degree. Nice, but the longevity of the mechanism is yet to be determined. I would appreciate it in a typical table placed laptop deployment, adjusting for seating height, seating and device distance too.
Typical laptop handling, the trackpad is MUCH BETTER than the Type Cover 2, it doesn't respond with a fickle delay in click or sliding. Being a smooth surface, it is akin to a typical touchpad, with a physical depression that ensures a solid click - unlike the "touch" clicking and "spongy" buttons on the Type Cover 2. I would still use the trackpad as a contingency pointing device, but it is larger and responds like one.
I haven't had a chance to sit down, typical seating chair settings, to really use the kickstand as one would be more inclined to use it as a typical laptop - but in more or less, both devices would be flat. Considering the taller vertical aspect, cover and Surface Pro 3 on my legs, it would be extending entirely on my legs. The cover would be propped against my stomach as I done with my Pro 2.
Due to the very bright area of the Microsoft Store location (a specialty store), I cannot gauge the viewing angles I would have be using it for, but it is bright enough to do work on, even if I am looking it from an extreme side angle. Brightness was set in the middle. I done this to see the gap distance from the cursor to the pen tip too and noting the angles of use.
As a Surface Pro 2 owner and user, I would be awaiting a bit after release. Those on the Pro 1, would appreciate this jump alone. Those on segregated devices - may like this convergence/price/consolidation.
