I will give it 9 out of 10. While testing, I found the matte screen surface is very nice and there is virtually no reflection.If you want to add more RAM in future, this is perfect for you.
It has 2 slots which supports 32 GB RAM maximum.The battery life is really long.
It gives backup from 4h 30 min to 5h running Adobe Muse, Illustrator, Photoshop, Word, Excel as well as browsing.
You can squeez 8 hours with low screen brightness.If you are a gamer,this is a thin and the cheapest rig for this specs.
The video card does great on high end games at top settings with no freezing.
Even if you are not a gamer, you can use this laptop for running high-end and resource consuming software for your task very smoothly.
Most of the people who buy this tells that the backlit keyboard is awesome.
The are a few negative reviews. Most of the ones I read were mainly about the display. The viewing angles are average quality.For some people, it is annoying while watching movies that are generally dark.
However, if you want to watch a lot of movie, you can replace the TN screen with ISP for around $50-$60 later.So, it is not a big problem for most users
Overall, Dell Inspiron i5577-5328BLK-PUS is suitable for everybody who want powerful hardware within budget.
