Why buttonless? I like buttons.

Heck, a scroll wheel would be a killer feature so I don't smudge the screen with my disgusting oils

Buttons and scroll wheels cost more than touchscreens at this point… 90s me wanted touchscreens on everything, and me since maybe 2015? has been firmly “bring back buttons”

…whenever they started replacing useful things that SHOILD be buttons always (car) with touch things. Absolutely not bueno.

The cheapest Pockeboot model always had buttons (and touch screen). The more expensive ones are always touch screen only. I never got it. Buttons are a nice feature, why remove them in higher end models?

It's not that they cost MORE, they can be sub-cent per unit if you buy enough of them:

Of course they cost MORE than putting all their functions on a tiny touch screen that’s already gonna be on the device!

Beyond manufacturing the device to be able to use separate physical moving pieces, you’ve also got costs supporting pieces that break in warranty, units damaged in shipping due to moving parts being tossed around, etc.

[–] frongt@lemmy.zip 11 points 21 hours ago

For just the part yes. Board design, programming, and manufacture costs increase with more components.

My Kobo only has a power button and it’s perfect for my needs.

My kobo has a power button, and two page turn buttons and its perfect for my needs.

Seriously, I have 4 (5 if you count the ancient kindle DX) ereaders, and the kobo is the only one I use. Will never again buy one without buttons

[–] PalmTreeIsBestTree@lemmy.world -4 points 16 hours ago (1 children)

It’s not that hard to tap the screen to turn a page lmao

[–] oats@piefed.zip 6 points 12 hours ago* (last edited 12 hours ago) (2 children)

Hard, no. Uncomfortable, yes.

I'm really not looking to move my fingers much when I read. What am I supposed to do, rest my finger on the display so I can turn the page and skip 15 words per page?

[–] PalmTreeIsBestTree@lemmy.world -1 points 2 hours ago (2 children)

You’ve never read a real book in your life?? You do that every time you turn a real page. Quit being a baby.

[–] Passerby6497@lemmy.world 2 points 26 minutes ago* (last edited 25 minutes ago)

At that point, why not just read a real book??

My whole reason for using an ereader is to eliminate the parts of reading physical books that annoys me, why would I buy a subpar reader that makes me do or simulates doing the actions I want to avoid?

Quit being a baby.

Quit acting like a child that thinks everyone should think the way you do.

[–] oats@piefed.zip 1 points 1 hour ago

Don't know what you gain by calling names.

Different people have different likes. Its really not a hard concept. Have a fine day 👋

[–] placebo@lemmy.zip 1 points 3 hours ago* (last edited 3 hours ago) (1 children)

You make it sound as if moving your finger a few millimeters to tap on the screen then back to the frame is as exhausting as running a marathon. My touchscreen reader is 13 years old and I never even thought about this process.

[–] oats@piefed.zip 1 points 2 hours ago

No, I didn't say exhausting, I said uncomfortable. I bought my first ereader in 2009, and a lot of then in the meantime, I had devices with only buttons, only toucscreen, and both.

Using buttons for page turns is the most comfortable for me. I do appreciate a touchscreen to configure the device, select books, etc.
