I've had an Asus 13" ultrabook for couple of years. And I am a travelling businessman.
DVDs... seriously? It's 2014. I suppose you carry your music collection around with you on CD too? Bad too for anyone who's still on vinyl as it also lacks a turntable.
My ASUS came with two small dongles, one to plug ethernet in and another to plug VGA into the HDMI port. But let's face it, hotels, coffee shops and airports all have wireless, so who really needs to plug in these days? I imagine like most business people, the majority of what I do online is email and web browsing. What docs I am working on are backed up to Dropbox, so a few MBPS internet connection is just fine for that.
I don't play games on the thing to be honest, so maybe it's not great on that front.
But it is light, thin, sturdy (metal chassis), fast (decent CPU and SSD).
My only criticism would be that like most laptops, the battery has had it after about a year, but since I typically use it plugged in most of the time, I can live with it.
