<p>Tigard-based InFocus Corp. unveiled a 55-inch, high-def Windows 8 PC this morning, doubling down on big computers at a time when most hardware companies are thinking small.</p><p>InFocus pitches the $5,000 BigTouch as ideal for digital signs, educators, and software demonstrations. It comes with Microsoft Office and a wireless keypad and a mouse, but it's designed to take advantage of the touch-screen capabilities built into Microsoft's latest operating system.</p><p>The new machine is a scaled-back version -- in features, not size -- of InFocus' Mondopad, which the company released in 2011. The BigTouch is $1,000 cheaper than the Mondopad and lacks the video conferencing hardware and collaboration software that comes with the Mondopad.</p><p>Best known for its digital projectors, InFocus was one of Oregon's very biggest tech companies during the 1990s.
