I’m a big fan of portrait-mode thumbing as a keyboard input method. I’ve used it for over 2 years on my Galaxy Tab and it’s been fast enough and easy enough that I’ve posted a large number of blog posts with it. The 10 inch Acer Iconia W510 with it’s light weight and 16:9 format screen offers something close although it’s not perfect. An 8.9 inch Windows 8 tablet might be the way forward due to smaller size and a potential sub 500gm / 1lb weight but for the time being, I’m prepared to accept this over the Galaxy Tab due to having the obvious advantage of having full Windows available if needed.
Here’s a video showing portrait-mode thumbing input that I made this afternoon. The video was made in a lower-quality 4:3 to test video editing on the Acer W510. Rendering speed for a 3.5Mbps output was 2X real-time which is acceptable for short videos. I’ll be testing Windows 8 video editing apps in the near future to see if I can find a process that is a bit easier on the finger too.
