I'm thinking about purchasing my first laptop. I've been using a smart phone for years and haven't really felt the need to get a laptop. I just built a somewhat powerful computer (i3-2100-3.1Ghz, 8GB, 1TB, HD5570) and really like it. But I'm moving overseas and even though my computer is in a tiny case, it still weighs around 20 lbs. But to get a new laptop I'm at a loss. Something that's comparatively powerful is usually very heavy. Everything else seems underpowered. I'd like something lightweight, powerful (comparable to my new computer) and if possible, nicely built/looking. A TV tuner would also be nice. I'm not really concerned too much with price, but I'm budgeting around a grand. Any recommendations? I would prefer a windows-based system.
