Good luck Chi!
Yesterday I managed to get my hands on discounted Opus from Waterstone. Not for myself but as a gift to someone else and I am currently testing it capabilities.
It is really a very nice device that I would like to keep it myself
The size is very convenient. It provides even more comfortable reading than 6" Kindle. The possibility to change font type is also a very nice feature.
Other features are less impressive. Accelerometer that is supposed to guess the orientation works too unreliably that I switched it off. The forward/back buttons on side can be transposed but sometimes it fails after waking up from sleep mode. So, I switched it off as well.
Dictionary support for mobi is there but it also works only partially. The bigger dictionary files didn't work and crashed the device. With some other smaller dictionaries it works fine but it is not the most convenient to use. One has to press too many buttons.
But if dictionary is not essential then this is a nifty device. Mobipocket firmware works with Russian and Latvian texts perfectly. It is not a Perl e-ink but the screen looks very nice that I don't notice any difference from Kindle WiFi.
For the price of £50 it is a perfect no-frills e-reader both for home reading and carrying around in a pocket or bag.
