The Aspire S5 ultrabook may be set for a Q2 arrival but Acer has something slim and portable for Q1 too, the Aspire Timeline Ultra family of mainstream notebooks. These upcoming 14-inch and 15-inch laptops are just 20 mm thick and pack an Intel Core processor, SSD/HDD storage, a slim DVD writer, Dolby Home Theater v4 surround sound, HDMI and USB 3.0 connectivity, plus a PowerSmart battery that will last for up to 8 hours per charge.

Like the S5 ultrabook, the Aspire Timeline Ultra models feature the Acer Green Instant On and Acer Always Connect technologies. And like the S5, these notebooks have not been priced.
