I want a phone in that size:
- Small.
- With touchscreen,
- With a browser
- With downloadable or even uploadable apps (basic ones like maps and messaging clients would be enough, don't need games or 3d, just don't want to rely on my operator or the manufacturer to create a new firmware before I can swap my messaging client.)
- A quick camera that is good enough for everyday pictures: whiteboards, messaging.
- Ideally somewhat water resitant
There’s an impossible trade off between being “small” as in credit card sized and having a usable browser.
I think it was quite a bit smaller than even iPhone 4 (I'm not really into Apple products though.)

Way to small, I want it to be practical for older people like me :-P

Kind of agree, but given the right phone I'd almost forget the browser on the phone and just use my laptop or carry a cheap tablet in my jacket for browsing.
Edit: yep
Thanks for your comment, now I am considering to get one.
The iPod has excellent battery life, and I've upgraded it with an iFlash SD adaptor. The iPhone 4S has a small screen, and removable battery on a Third Rail case.
I had a quick look last week after the iPhone SE was discontinued. The highest small-screen (3.5") resolution is the iPhone 4 display (960x640). It's even higher than newer phones, according to dpi.lv. The best Raspberry Pi screen is 320x640.
What we as hobbyists need is a 3.5" RPi touchscreen module with higher resolution. Then the iPod modding community can provide a case, and Seeed can provide a phone. The problem is, I couldn't find anybody manufacturing high-res small size touchscreens.
RPi only supports 2 lanes of MIPI DSI interface, iPhone 4 screens (that are still manufactured and offered for $5-15 on aliexpress) use 4 lanes precisely because they are higher resolution.

No idea what the quality is like (probably not amazing), but the Chinese appear to still be making various rather small Android devices, including iPhone 4 clones.
