What atrracted me to the TrekStor Pyrus Mini was its size. I've been looking for an ereader smaller than my Kobo Mini for when I travel. I bought the Kobo Mini ($50 on sale 2 months back) because it was smaller than my Sony PRS-350.
The lack of wi-fi on the TrekStor Pyrus Mini is fine with me. I always keep wi-fi turned off on my ereaders to avoid automatic updates and save power, and sideload everything. I won't need to take notes on it, or highlight, just have it fit in a shirt/trousers pocket for reading epubs on the go.
I love my new Kobo Mini and it's become my daily reader. The Nook STR was too big and it's being used by a co-worker.
