The Trekstor Pyrus Mini
now seems to be available for €49.99+p&p.
There's a review over at The Digital Reader
"This beauty is shorter, narrower, and thinner than the beagle, and it weighs in at only 111 grams, beating the txtr beagle by 17g and the K4 by 59g. The Pyrus Mini is being sold by trekstor, and it has a 4.3″ E-ink screen, 1.6GB of accessible storage, and a microSD card slot."
The screen is 600x800 pixels, which works out at 232ppi.
