Acer unveiled the stylish All-in-one Acer Aspire Z5600 PC featuring a 24 inch display.
The Acer Aspire Z5600 is already aimed at leveraging the touch features of Windows 7. Acer highlights that the Aspire Z5600 will be a mainstream affordable PC. I guess they highlight that to hit at Apple and their also extremely stylish albeit no touchscreen featuring iMacs.

Acer is not specifying if the Z5600 is actually featuring a multi-touch display. Gizmodo says it does.
Other features of the Acer Aspire Z5600 include up to 2GB HDD, MXM graphic processors, Intel CPU, TV Tuner, and DVD/Blu-Ray player/writer combo drive.
It is not clear if Acer is launching the Z5600 earliest when Windows 7 comes to the market or if they are also going to ship it with Windows Vista.
