Well I can promise you that my 2014.86 euro laptop is a reliable alternative to my desktop
Battery last around 8 hours (depending on usage) (and it switches off when powered by cable), it runs anything I want and its fancy pancy
Nah, I primarily bought it because I need it for 3D modeling in relation to work, but for gaming it also serves its purpose. And that is quite useful for lan-events or similar.
Granted (as already said): getting the same for my desktop as I got on this one could have saved me some money, but I needed the mobility (so thats a huge + for it). Bring it along on a holiday and so forth.
Only problem with the damn thing: the one I bought is basically a replacement desktop in laptop form so its quite heavy and it has a huge transformer.
My next update of equipment is however the desktop as it has passed its 2 year marker.
