Ehrm. I really hate to say this, but if you plan to have GNU/Linux on this laptop, then I think you should be better off. Ok, that's a not really good start, is it? Sadly, I would rather pay $20-40USD more rather than to have AR8162, as an Ethernet NIC, and BCM4313 for a WiFi. Because it seems to me like these two things do spoil otherwise great and snappy configuration.

I mean, Intel i5-3210M Ivy Bridge is quite good, 4GB RAM is enough and expandable, 1TB HDD is more than sufficient, battery time - I haven't tested that yet nor probably will, GT630M 2GB will be able to handle some games, so why oh why Lenovo, why have you spoiled the experience at connectivity front?

AR8162 is only 100Mbit/s NIC which is, for normal use and “standard” internet connection, and isn't enough, compared to all Gbit/s NICs out there. It also doesn't have support in Linux kernel at the time of this writing. Broadcom's BCM4313 a/b/g/n is another pain. Despite it seems you have couple options how to make this card working, actually the only one half-worked for me. Sadly, it was Broadcom's proprietary(?) wl driver. And why half-worked? Why the pain? Because it works only in the US reg domain and the only available channels in 2.4GHz are 1-11 which is fine, unless you live in EU, you have an access point sitting at channel 13 and you can't change the channel. Then you're out of WiFi. Really, I would rather had an Intel WiFi and something else for Ethernet NIC.

Yes, the above is kind of rant. I admit it. However, what I really don't understand is DVD drive. I'm sure drive itself is fine, however the plastic cover is ruining it. And you have to really push it to get the doors closed. It is almost as they don't fit, or there is some (extra) locking mechanism. It that case, it is likely it's going to break some day.

Other than above, I find Lenovo G780 to be satisfying and I think it has great potential as desktop replacement. What else to say? LCD cover seems to be made from hard plastic and doesn't give in. Surroundings of keyboard are made from some kind of metal and have a nice and cooling effect. Keyboard seems to be ok as well, although I can't get used to layout and would welcome bigger 'Enter' key rather than numeric keypad. Normal size touchpad with two-finger scrolling, no trackpoint, 2xUSB 3.0, 2xUSB 2.0, HDMI, VGA and that's about it.
