"One would thing that such an universal interface would quickly become a standard offering in airports, hotels, libraries, conferences, etc."

My favorite computing peripheral form factor has always been the PCMCIA card.

It seems to me that you could fit a minimum viable phone inside a PCMCIA card and then insert that PCMCIA card into a normal sized laptop when you choose.

The laptop would have no CPU/RAM - it's just a big USB keyboard and monitor - and the phone would probably have limited battery life, given the size (although you could bump out the non-port end of the PCMCIA card with some extra battery, the same way that wifi cards had an antenna bump ...)

Something like this was proposed ... there was some minor project where they had built an entire PC (not a phone) into a PCMCIA card (although with different pin-outs) and proposed using it as a portable "guts" for any laptop "host" but I can't find the URL for that project anymore ...

I certainly would welcome a phone the size of a pc-card and a cable-less docking of the brain into the host laptop would be much better than either 2-3 USB cables or some weird, proprietary phone dock ...

I think you're thinking about the EOMA project. Boards are soon to go out for their production run.

Yes that is indeed what I was thinking of - it's a very interesting project.

Imagine if that device was a fully functional, standalone phone ...

I don’t understand the desire for this. In this model, you’re still carrying a laptop. It’s just utterly useless without the phone.

The use-case is in the opposite direction: when I only have my phone, I have my entire computer with me - including the storage and the files and keys and so on.

No syncing required. You only have a single computer. That's a big win, I think ...

If you care about the stuff on that computer, you really want it synced somewhere anyway.

I don't personally see the utility in having my phone be my computer. I don't need Visual Studio or Photoshop on my phone. If I don't have my laptop/desktop, I'm not going to work on the things I typically do with a full-power computer. The phone is just not the right form factor, so it doesn't help for that stuff to be on my phone.

"If you care about the stuff on that computer, you really want it synced somewhere anyway."

I disagree.

If you care about (stuff) you really want to back it up somewhere.

This is different than "syncing" which can mean anything, is usually a completely unintelligible process for the end user, is fragile, and is actually a hard problem.[1]

Much more intelligible and manageable is to have one single repository of data and carry that "kernel" of stored data everywhere. Yes, certainly you should back it up, but the backup is just that: a point in time backup that you do not operate against.

[1] Two way sync, dealing with new, but different objects on both devices ... this is not a "solved" use-case ...

There is the ASUS PadPhoneX

The REXX? I think it was made by Rolodex or something.
