Currently, I'm using a Sony Vaio E Series VPCEH18FG (you know, the one with the geometric surface thing). I've been using it for the past two years, and I'm not really having problems with it, but I'm looking to change to something lighter as the Sony Vaio is too heavy for my lifestyle (travel, commuting etc.) and using a netbook has really not worked out for me.
I initially intended on buying the Macbook Air, but I think its maximum storage capacity (256gb) is too small for me and just too expensive for what I'll be getting.
Hence, I thought an ultrabook would be a better option--though which one, I have no clue.
As already implied, a lightweight build and higher storage capacity (I currently use about 250gb on my 500gb laptop) is sought after. A decent amount of ram (4gb min.) and a good processor (i3/i5) is obviously important as I'd like to have a pretty good user experience with it. My maximum budget lies somewhere around $1100-$1200. I'm not particularly picky about design or brand.
I know my budget isn't huge in light of what I'm asking for, but any suggestions would be highly appreciated.
