I hope Logos 4.0 has tablet/touchscreen pcs in mind. I use my asus 1000h netbook (with touchscreen) with logos during sermons and bible studies. I rotate the screen 90 degrees and hold it as if it were an open book. The 1024x600 screen is actually nice in portrait mode when using Logos. I just wish it were easier to manipulate the text and navigate using a stylus or finger.
Adobe acrobat has a full screen mode in which I can read texts in portrait mode and drag the text around and navigate using a finger. I would like to see a full screen mode in Logos 4.0 that is even better to navigate with a touchscreen. If there were a touchscreen mode with easy to manipulate navigation buttons I'd be recommending it to my friends with touchscreen netbooks.
