The realistic part:
1. Have page turn button on bottom like prs-t1/pocketbook touch lux series.
Sometime I hold using left hand, sometime using right hand, this button placement allow gripping like real book and can be used with either hand
2. front light, with easy on/off like aura HD, or even intensity level like inkpad 840
Sometime I read outside when it is already night and this will be nice to have feature. The intensity should be able to set at very low. I always use 1% when I had the aura hd.
3. Splashproof with with lockable touch screen (maybe like h20/aura one but with extra feature)
It would be nice to be able to read during drizzle/ rain. No worry for damage and no accidental touch. Button will be required to operate.
4. External micro sd card
Just in case I need more storage, or even split the collection to different microsd to make the collection looked cleaner in the reader (i.e, have a separate microsd for manga, IT books with each have different genre set).
5. Scratchproof / hard to break.
6. Decent battery life. At least 1/2 month reading for 30 minutes a day like most e-reader is fine with me.
Now the unrealistic part:
1. Can shrink/expand as needed. If I read walking, I would prefer 6 inch. If I read while relaxing at bed, or reading comic, I would prefer 8 inch. If I read pdf document I would like a 13 inch one like DPT-S1 with stylus for taking note easily.
2. Can either be 1600x1200 grayscale for sharper text like inkpad, or 800x600 color screen like color lux. It would be even better if it can be done without reducing resolution, and just a toggle to render as grayscale for less distraction. This is mainly for occasional color page or color coded text in programming book
3. Not that expensive, not that hard to buy
