Amazon may be happy to keep selling the four-year-old Kindle Voyage but the same is not true for its smaller competitors. The Polish ereader importer ArtaTech has updated its two-year-old Inkbook Prime ereader. The new model has a higher resolution screen and (possibly) an improved frontlight.
The Inkbook Prime HD runs Android 4.2 on a quad-core 1.6 GHz CPU with 512 MB RAM, and 8GB storage. It has both Wifi and Bluetooth, and packs in a 2Ah battery.
The Prime HD appears to be almost identical to the earlier model, but it does have a few improvements. The screen resolution is now 300ppi, compared to 212 PPI in the original model, and the specs now mention a frontlight "with light color temperature management".
Judging by the Inkbook Lumos which I have had for a week now, the frontlight on the Prime HD will be much milder than you would find on a Kobo model. The frontlight on my Lumos review unit ranges in color from a blue-white to a pale yellow-orange. I find that to be more than enough variation for my tastes, but then again I never really liked the stronger orange color settings on Kobo devices.
I am less pleased with the Lumos's general poor performance, but the frontlight is quite nice.
You can find the Inkbook Prime HD in ArtaTech's store, where it retails for 139 euros.
