What happen to you 4820tg? I am currently using 3820tg, still strong and nothing wrong with it.
It's thinner than my 3820tg. It should be much thinner than 4820tg. According to
spec: Height: 30.40 mm
V131 is 21.00 mm.
Other advantage including USB3.0 and e-Sata. Both allow you to use external HDD at 10 times (theoretically) faster. With this option, it is now possible to install a small SSD (cheaper) for OS and application, then keep all movies, VMware, etc in an external HDD. You can access the external HDD at full speed.
V131 has faster HDD (7200 RPM), 2 hours more battery life with wifi, Sandy Bridge CPU and there is also a finger print reader... but i dont use them... the Webcam is a HD webcam, much better than most web cam.
The difference between i3 and i5 in most daily computing are not noticeable; even in running a few VMware and gaming. But i3 should run cooler.
But since you already have 4820tg, I recommend you keep it. V131 is no match when it comes to gaming. The 5650 / 6550 GPU in 4820tg will make V131 cry.

my hard disk failing.. S.M.A.R.T reporting hdd going to fail.. lucky I have few months before my warranty period over.
I have few other complaints like lid not closing properly and noisy fan even when not gaming, keyboard trapped so many dust and it flexes.
I have desktop already for gaming, and I don't like gaming in laptop coz the fan will kick in, laptop feel hotter and I feel like my laptop under stress
I use my laptop mainly for java programming, that's why I require to have i5 processor, and the portability of the laptop means I can do programming more on the go. u have explained more advantages v131 have compared to 4820tg. but then when it come to my senses, maybe I should just keep the acer. dunno
