In May 2004, Sharp announced an ultra-portable version of its Mebius Muramasa notebooks, the PC-CV50F (the black version; the white one was designated PC-CV50FW). This curious machine has a 7.2-inch "WonderPix LCD" that uses ultra-high aperture ratio technology (whatever that means) to achieve a groundbreaking resolution of 1280 × 768 pixels, accompanied by high brightness for crisp detail. If that's too crisp for you, just press Fn + F2 to switch to 1024 × 600 pixels.

The Muramasa PC-CV50F measures 225 × 158 × 30.1–31.1 mm and weighs 880 grams. It does indeed feel like a successor to the Telios HC-VJ1C from early 2000, which had a 7.1-inch 800 × 480-pixel display, measured 213 × 140 × 28.3 mm and weighed between 820 and 860 grams.

Although intended for the Japanese market, the PC-CV50F was designed by Tom Schönherr of the German design studio Phoenix Design.

It is powered by a Transmeta Efficeon TM8600 processor clocked at 1 GHz and has 256 MB of RAM (upgradable to 512 MB) and 20 GB of onboard storage. An ATI Mobility Radeon graphics adapter handles graphics processing.

The PC-CV50F has a built-in Wi-Fi 802.11b antenna, two USB 2.0 ports, a CompactFlash Type I/II slot that can accommodate a PHS modem, an SD card slot, an external display output and a DirectHD connection. The latter is particularly interesting because it allows another Windows PC to access the Muramasa's hard drive as an external drive, even with the lid closed, making synchronisation and file transfers quick and easy. The notebook can also wake from sleep in just five seconds at the press of a button.

This ultra-portable Muramasa came with a remote control for one-handed music and video playback, as well as photo slideshow control. But this was a serious step down from the LCD remote control with headphones supplied with the Telios HC-VJ1C five years earlier, which also let you read emails and other notifications. Surely Sharp could have done better!
