Sony is taking on HP's TouchSmart family with a touchscreen-equipped all-on-one PC line of its own.

Due to debut in July, the Vaio J series sports a 21.5in display with 1920 x 1080 resolution and "multiple lamp" backlighting. It's driven by a 2.26GHz Intel Core i3-350M processor and an Nvidia GeForce 310M 512MB graphics chip.

There are 4GB of DDR 3 memory on board too, plus a 500GB 7200rpm hard drive, a multi-format DVD writer, 802.11n wireless networking, Bluetooth and a webcam.

Sony highlighted Vaio Gate, a Mac OS X-style media and apps dock that sits at the top of the screen, and YouPaint, a kid-friendly touch-controlled art program. Both will come bundled with the PC.

How much all this will cost you, Sony isn't saying, but it did say the J will run Windows 7 Home Premium 64-bit.
