This laptop is quite good for normal office use. The Celeron 1.8GHz version is not necessarily slower, because it features a newer Ivy Bridge architecture. I have that one myself. The new one also features a usb 3.0 slot.
I bought an E1-531 on January 5 2013 for home use and on April 12 2013 it just went bye-bye, darkness nothing works. How`s that for long lasting performance? Will I purchase an Acer again mmmmmm... maybe not
I have an E1-531 g with geForce 710M, and it's work briliant. I'm using it for 3D graphics, programming and gaming and music production and it's fantastic. A lot of new games work perfect on mid/high details, system runs very fast, i haven't any problems with wi-fi, bluetooth.
But case looks like crap. Cheap, soft, glossy plastic everywere. I'm afraid when I must take it to rucksack. 2 days later after unpacking it, i had a lot of scratches. And that glossy screen...
Battery perfomance is not perfect, but not bad. While surfing the internet, battery is out after aproximatelly 3 hours, on gaming 1 hour.
Overlay: Budget laptop with very good perfomance. If it'll be stolen, I will buy it again.
