We've had one since 2009 that has been an amazing laptop. My Elitebook 8760w (work laptop) was a piece of crap. I would consider spending my own money on my replacement work laptop, an Elitebook 840 G2 - very impressed with it.
How about Acer aspire v3-574g 15"? Its packing some decent specs and I think it would be enough for basic editing. But are Acer laptops bang for the buck?
Which model are you looking at? I see them with a i5-5200U and i7-5500U.
Both of these are 2-core, 15W low-power, low-heat, long battery life chips. They deliver very well for that, and basic computer tasks; however, they don't have much grunt when it comes to raw processing power.
For video editing, you should be looking at a "HQ" or "MQ" 4-core processor like the i5-6300HQ or i7-6700HQ.
I've been using a lenovo ideapad z580 with a 2nd gen i3 dual core 4gb RAM and gt630 gpu with an ssd for on the go editing purpose, it performs decently for basic editing. So in comparison to that I'm guessing this would be much better. Right?
Look at Haswell-based laptops, then. I wouldn't use a U-series processor for video editing. They usually come with very poor cooling solutions that will throttle speeds when worked hard for long periods of time.
