Well, if you can live with certain quirks

The 591g was supposed to be a direct hit. Mine had not described so many quirks like many others. My old laptop, a MacBook Pro 13 '' from 2011 (under Windows) is available to the detachment, some aspects I will be compared to the MBP.
In my copy of the touch panel was installed properly and the display was completely OK. This model is not one with ac-Fi and also has the problems often described

CONTRA:
- The bad responsive touchpad was already criticized in many reviews, including mine made problems and responded by late or not. Said, was better during the 10 days that it was with me. The touchpad has a kind of braking coating, but rub off quickly when used. After that the response was better, but compared significantly worse than the MBP.
But you get no setup tool for the touchpad to do so. What I have so culled from my forums is that it is a Synaptics touchpad well, but internally this non-USB Special anything else is connected and thus the normal Synaptics driver is not working. The Acer but offers only basic functionality and no configuration option.
But the KO criterion for me: Adobe Lightroom has problems with Synaptics touchpad. You can not scroll gesture by two-finger it.
This can be hinbiegen in the normal driving by a few registry settings, this however, there are not in this model. Lightroom is for me but one of the most important applications and the reason why I wanted a powerful device. This will perhaps at some point fixed times, but because my Wiederruffrist expired, I returned it.
- The battery life is a joke. For surfing and email via WLAN with one probably. max. Min.5 video portion maintains a full battery no 2h. I have always fully charged and then fully discharged him, but after 10 days was not the better.
- The ventilation system looks good, but is not practical for use on the lap. The outlet openings are inclined downwards to the rear / close attention to the legs. Now in the winter, I once had a blanket over his legs and the notebook on. It began to boil, because the blanket covering the ventilation. If you use it no problem on the table, but not practical for me.
- After a week the unit made squeaking noises. It was the left hinge, and when in motion, the display teeters minimally, it creaks from the hinge.

NEUTRAL:
- The display is quite OK, very good anti-reflective coating and thus even in sunlight still usable. The maximum brightness is higher than that in the 3 years old MBP. The sharpness is very good. It's something of view depends on what does not bother me personally. The display from ASUS N551JK is still crisp and less viewing angle dependent.
- The keyboard is alright, similar to MBP. There are better, such as the Lenovo Flex 2 Pro. From the pointed keyboards of Thinkpads times not to speak. But completely OK, the red light is pleasant enough and does not see prollig from what I had initially feared.

POSITIVE:
For those who have persevered to here: Actually, the rest is the device really great.
- Performance: top. Lightroom starts in about 2 sec. On the MPB that lasts more of a minute.
- Slim and lightweight: other devices with similar performance cost much more, are much more massive, or both.
- Although there is a black plastic device, it looks very valuable and attractive
- Outstanding options at the Speicheraustattung: 256GB SSD + 1TB HDD + 16GB RAM, who else has the still like that?
- Software: little bloatware and what you do not like is deinistalliert quickly. The Acer's proprietary software like it very much. Maintenance, Tuneup, software updates, support link all in one sleek application. Very good.

CONCLUSION:
It could have been my preferred system. The ventilation system, the battery performance, the creaking and the responsiveness of the touchpad I would be able to live, even if the for a system in this price range already should not be so. But all devices so have their quirks. Perfect is not a notebook for me and you have to look with which quirks you get along halt. But that I can not use Lightroom, the KO criterion has been for me then. How many stars I give it now. It is in total a very good device, definitely above average, more than three stars. Five were due to the quirks too much. And who Lightroom uses or mobility studied (but then you do not buy equipment with i4710, but rather what with power-saving CPU), which buys another device. 4 stars from me.
