Yes, they could be used. However, the TextBlade was a solution the the problem of migrating from a Windows laptop computer to an Android smartphone or phablet pocket computer for ultralight international travel.
Besides not being able to get the TB in my hands yet (for which I have cancelled my order), by the time I cobble together hardware solutions that were designed for use with laptops and tablets, I’m actually lugging around more pieces of gear that are all together heavier than the laptop I’m trying to replace. And, the kicker is I’m still no where nearly as productive on any android tablet as I am on my old, yet very functional Windows 7 machine – a very capable Acer 1830T 11.6" laptop with core i7 processor that, with SSD, is just at 3lbs and only cost less than $300 total! I actually find the mini trackpad on these machines more productive as I can reach anywhere on the screen with one movement of my thumb, whereas the same movement on a larger track pad can often require multiple movements.
The suggestions of solutions need to keep things in context. If I have to lug around separate trackpads, wireless mice, etc. that are bigger and heavier than what I can purchase now on Amazon for under $16 (bluetooth keyboard with trackpad for windows/android @ 9.3oz), then I’ll say thanks, but no deal. I just received and am now testing such a device that provides me a working keybaord AND multi-touch trackpad for not much more weight than this keyboard-only TextBlade.
In the end, the solution for me lies in the next iteration of the Lenovo (NEC) LaVie series of i7 laptops at under 2lbs. But until they get teh battery life closer to 10 hours, I’m not plunking down $1500 for one – not yet.
I would have like to think I could just pair a TextBlade and ultra-mini/ultra-light trackpad to my smartphone for the ultimate in pocket travel, but until I find a 2"x3" bluetooth multi-touch trackpad for under 3oz and under $50, I don’t think I’ll do better than this little $16 bluetooth keyboard. It doesn’t fold, but it will fit nicely into my 17 liter backpack. And that, for now, is about as close as I’ll get to my ideal solution.
