Your Dream phones / tablets??

most of what you want already exists. for an all in one device have a look at the soon to be released android superphone called the samsung nexus.

not counting hardware specs, the only things it will not do are:

-act as a fm radio, however you will be able to get internet radio
-have an 11" slide out screen (impractical if you think about it)
-have a slide out keyboard (other phones do though)
-be controlled by a computer

some people report such battery use currently. it all depends on what phone you have, how much you use it and what your settings are. if you use gps, bt and 3g all at the same time with your screen at 100% then you are going to drain it no matter what battery they put inside. well unless you want to carry around a 5 pound brick.

Sorry but I cannot see anything impractical about a slide out screen. As i know Nokia and samsung with samsung amoled flexible screen is almost there.
Remember that the phone in daily use is not bigger than the phones now-a-days
Only when you need it you can slide out the extra space.
Very practically - particularly when you are really think about it ;-)

And remember this is just a dreams of the future

Uhm...practically all of that is already here. My iPhone 4S is 100% capable GPS with an app I bought called Navigon, it takes better pictures/videos then any point and shoot I've ever had (only issue is shutterspeed). Its obviosly a telephone, and can do almost everything my laptop can plus its got an ipod in it.

Realistically speaking, my dream phone would have the following:

4'' OLED Screen with 720P Res (370PPI)...Why?...perfect color accuracy, contrast, resolution, and super efficient.e
Quad Core CPU...Why?...multi-tasking
4GB of ram...Why?...lots of new apps, games, and utilities are getting very memory intensive, on top of the OS's being memory hungry with all the features, more ram cannot hurt.
Faster SSD Drive..Why...? Faster booting and opening apps. Generally more responsive.

Camera: I'd like a 10MP camera with a large lense, flash, and faster shutter speeds. Also, 1080P Video is fine, but 60FPS would be a big improvement. 30FPS just isn't enough for video where you need to change landscape even slighly faster.
Front facing camera would preferably be 720P video and 5MP shots with flash also.

A GOOD PRE-AMP: I have yet to listen to a phone with headphones that has a decent headphone amplifier. The sound sucks. I'd like the headphone amp's to be a bit better quality.

What I want is truly realistic.

PS: I'd take a 720P camera at 60FPS over a 1080P Camera at 30fps. 720P excellent resolution, but the extra 60fps would make a HUGE difference.

My dream phone should have a laser projection keyboard, just like the animation iphone 5. Beside, it should integrate all the needed cell phone accessories in it so I don't need to buy extra.

My dream phone is android phone. i really want to own this phone. and luckily, my brother bought is for my birthday's gift. i am so happy for that.

I posted this on somewhere else before. But this one have some modification in it.

Totally unrealistic? I know.

If I try to see the more realistic part of your dream Phone I will point out following point I really think are good ideas:

- Window 8/ubuntu dual boot (I like to add: Windows compatible)
- Enlarged rubber rounded corner
- Dual sim
- USB 3

I will add those point to my list of point for my dream Phone - which is almost realistic

12 MP camera - I don't think it will give you a better camera - The issue is the lens quality

That is why I said Carl Zeiss, slr and x10 optical zoom

@op

while i do agree that a pull out type display would be very handy... there has to be some sort of support frame around it or its going to flop around and be useless. however, using this as a touch type device might prove tricky as it has almost no thickness. i'm not against the idea of such a device being included in phones, just that it needs to be practical.
