The LG Z350 Ultrabook has been announced. Based on the same chassis as the LG Xnote Z330 it looks like a straight upgrade to Ivy Bridge to make a 2nd-generation Ultrabook.
Update: The announcement includes a new 14″ model. The LG Xnote X450
LG haven’t come up with a full list of specs (we suspect that will surface next week during Computex) but are pushing a thickness of 14.7mm which is tenths of a millimeter thinner than the Acer S5. This is getting silly! Taking a look back at the Xnote Z330 specs we also see a claimed thickness of 15mm so maybe the Acer S5 was never the thinnest anyway.
