I'm not worrierd about not being able to use the software (I'm a windows user and not at all shy when it comes to handling software...even Sony software...^^) but about what it actually supports...
I have not seen .txt mentioned anywhere...it just says "more text formats"...why not go ahead and say what you really mean...and why do you have to convert it? Hanlin and iRex offer native PDF and .txt, .html support and offer the conversion as an option. (at least Hanlin does, iRex does not tell).
The iRex also makes it possible to use the device as "USB-Storage", meaning you don't have to install some proprietary software...good if you like to pick up documents from different computers...installing the software on each one is not really fun...and I hate synchronizing...it's ok for contacts and schedule, but it's pretty weird for actual content (aprt from daily newspapers...)
The Hanlin probably uses a conversion/transfer software as well...but I guess it'll be a lot less "invasive" than the Sony version...we'll see.
I contacted Hanlin (Jinke) and iRex for details...let's see whether they reply...
