Mobile Phone as Home Computer?

theodp writes "Citing millions of Japanese consumers as proof it can work, MIT's Philip Greenspun hasissued a call for comments on his hypothesis that the mobile phone can function as a home computer for a substantial number of consumers if it's paired up with an appliance that drives the phone from a full-size keyboard and display."

No

So what he's saying is... the phone makes a good computer if you fundamentally change it's features? A full sized keyboard and monitor are not pocket sized. Pnoto.Net, Greenspun's own site would be a very different experience on a pocket sized device.

Small mainframe or big calculator?

[Dogtanian]

From the article:-

The PC is a scaled-down circa 1965 mainframe.

Actually, it's been argued that the microcomputer/personal-computer is actually a scaled up circa 1971 calculator; the first microprocessors were designed for calculator use, and the first microcomputers were exploitations of these by hackers who wanted their own computers. They weren't designed by someone trying to scale down a mainframe, they evolved from someone trying to build a computer from a crude microprocessor.

But that's perhaps disingenuous; I think what he is referring to is the OS; and it has to be said that as they grew in power, personal computers took their cue more and more from powerful mainframe/minicomputer operating systems like Unix.

Am I the only person...

.. who thinks that this endless pushing of features onto our mobile phones are stupid?

Why turn our phones into games consoles, video cameras, mp3 players, computers and whatever else we can fit into it, if it doesn't do anything well? We've got digital cameras that can play mp3s badly, mp3 players that can take photos badly, phones that play mp3s and take photos badly. Most people I know who want to listen to mp3s will use an ipod or zen, since the quality is higher and they have more storage, and most people I know who actually take many photos carry round a digital camera. Most people I know who have a camera phone have used the camera only once or twice.

On my ideal phone it would have a phone book, ability to phone people, and the ability to function as a modem for my laptop. Just a plain old black and white screen would be fine though. Maybe there should be an ability to keep a small diary/timetable on it, since we carry it round and it could function as an alerting device.

A laptop is still a laptop

[ajgeek]

It doesn't matter how small our laptops get on the inside (save for cooling purposes), it's still going to have a keyboard and a full sized screen. WE aren't getting any smaller. A mobile phone with a keyboard and a full sized screen is... a laptop, except that it's auto-connected to a wireless phone network.

Why phones work in Japan

[Bushcat]

There are some whopping assumptions here, so bear with the broad brushstrokes. Yes, internet on phones works in Japan. But Japan is way different to the US.

1) Most people aren't at home most of the time (this is the worst generalization, but it works). So most people are not sat in front of their computer, most of the time.

2) Most people have long commutes.

3) Most people don't commute by car, so have time to play with the phone.

4) PDAs don't do well in Japan. Most phones have PDA-like features, which means there is no need for PDAs but actually this is wrong because most phones don't synch with computers in any meaningful manner (and I'm looking at you, Sharp. In fact, while I'm looking at you, Sharp, I'd like to ask how it's possible for you to engineer such ill-conceived user interfaces into your phones time after time after time. Maybe you need to think on this when Vodafone finally gets a clue and asks Toshiba to lead with new-generation phones. Not that Vodafone will be around in Japan much longer unless it stops the ex-pat/in-pat/Japanese in-fighting and gets to grips with the way its phone providers make better phones for the competition than for Vodafone. Hello NEC).

5) Cellphone charges are pretty low, in the great scheme of things, so people can use them as recreational devices.

6) For several of the above reasons, phones are used to coordinate meeting up after school/work, are used on trains where voice is banned, and use to access content to pass the time commuting. They combine elements of recreation and communication tools.

In terms of business models, i-mode is more business model than technology, and the i-mode approach works well where it has been introduced outside Japan. Compare that with Vodafone's idiot Live! service, which is painful in comparison.

Well, not enough infoi there to sway anybody, but I'm in the industry and cellphones can be personal computing devices, but only in some or the majority of cultures. I don't think the US is one of those cultures right now: phones are utility devices, rather than fashion statements and recreational devices. Nothing wrong with that. But I think in Japan, gadgets are likely to be in the pocket, whereas in the US they're more likely to be on the desk.

There's a few reasons why voice control probably won't obselete keyboards.

• Speaking to control your computer is quite tiring, I know, I've tried it.
  
• Try concentrating in a 10m square room with 5 people all using voice control.
  
• Try playing counterstrike saying 'turn left 3 degrees while panning up 4 degrees and duck then fire'
  
• say this : for (int i=0; i bar(&q); }
