How Small a PC Is Too Small?
Banner~! recommends an article in IBTimes on the search for the ideal size for an ultraportable computer. One device mentioned is Paul Allen's FlipStart, discussed here recently. After watching early users fumble and nearly drop an early version of the FlipStart while trying to perform a three-finger salute, designers ended up including a single key labeled "CtrlAltDel" in the version that will be shipping soon. From the article: "Each device maker... has a different sense of how small an ultra-mobile can get before it becomes impossible to use. For instance, Microsoft thinks the tiniest screen possible measures 7 inches diagonally, but FlipStart Labs settled on 5.6 inches."
There are shills on slashdot. Apparently, I'm one of them.
That's too big an OS. Or at least too big an interface.
This should be obvious. Does it really make sense to load a huge OS like Windows, with all its carryover behaviors for backwards compatibility, for something that really should have its own methodology?
You're not having a problem with resolution. It has nothing to do with 1200x800 or any other screen resolution. Instead, you're having trouble reading the text because the font size is too small.
The size of the actual computer is of absolutely no importance whatsoever. What matters is the size of the input and output components. These are the interfaces to humans and must exist on a human size scale, i.e. large enough to handle.
So as long as you need a keyboard, the keys must be large enough to press, and the entire keyboard must be large enough to comfortably hold. But if you think virtual keyboards, i.e. one projected into the air, on a HUD, or on a table (the later exists as a Palm Pilot accessory), then the size of the actual hardware again is irrelevant, the size of the virtual "keys" is what matters.

Let's do the math. A pixel count of 1024 across and 600 down is about the minimum you need for there to be any point in the computer running a full version of Windows. Above 100dpi and you're going to need to increase the default font sizes (which means its fairly pointless to go any higher). End result: 11.87 inches on the diagonal is about the minimum for anything serious. Below that you're going to need better than average eyesight or you're going to be scrolling sideways all the time.
There is no realistic way that a PC can be too small. As long as it so small it is easily lost it is just fine - I would *love* one that could hang on my key chain.
What *can* be too small is the interface. I do not like a tiny screen nor do I like a tiny keyboard (or other input device). I have quite large hands, even the smaller "full size" keyboards are uncomfortable and only useful as a portable device, not my main one.
I have seen keyboard solutions that are OK - some project a keyboard on a flat surface and optically(? I do not think the descriptions said and I have never used one and that seems about the only feasible way) sense where you fingers hit. Other than some RSI problems with my finger hitting a hard surface (and that is fixable for a permanent station) that can be made to be any size or layout.
I also prefer small text, but I prefer that on a larger screen. I am currently using a 15" LCD and that is about as small as I comfortably go. I do not like writing much code in it either, my 21" monitor went kaput and this is all I could currently get. A 17" screen is the smallest "normal" lcd I like and I prefer a 19". I know of no current technology to fix this one, but there is no reason it can not be fixed.
Of course, that is for what I would call everyday use. If your computing power is in a small package there is no reason you can not have a docking station for full size stuff and quite small for carry around. I *can* hit some very small keys with a stylus and use a very small screen (lets face it, many of us currently do - or did - with the palm tops). That is nice for something I pull out of my pocket and use for a few minutes. Add in a few larger keys to mash and I can even game, navigate for MP3's, use a cell phone, add something to a calendar, or other typical small device things with large easy to use buttons. At that point I would consider the size my finger can reliably hit and the number of buttons to be the limit (small could use a stylus, but I do not like that idea for simple frequently used functions).

I second this opinion.

Almost 3 years ago I opted for a "converged" phone, a Samsung SCH-i700 PDA phone from Verizon. It was pretty nice, but DAILY use exposed the shortcomings of using a handheld as a phone. Yet there were times that the device was pretty damn convenient, when I needed to Remote Desktop, VNC, or get a "more featured" browser.
Nokia realized that putting a phone in a PDA is dumb, and they have avoided this mistake in their N series tablets. Until wireless data is universal and cheap, there's no point building the expense of a PHONE into your PDA. There's even less point in using a PDA as a phone.
Things are better today -- you can get a "normal" phone with data, and bluetooth modem support. Your PDA becomes "agnostic" about who provides the data layer - 802.11, bluetooth, or the US cell phone cartels. It doesn't matter anymore. Now you have real choices.
The Nokia N800 is the closest thing now to a perfect portable Internet tablet. You don't need to know Linux. It just "works". Developers are finding the device is a DREAM to develop on, combining Linux + GTK to make an open platform for anyone to use and develop on. Desktop Linux apps are being polished and ported over. And applications like 'Maemo Mapper (GPS)' are awesomely free.
You don't get a lot of free apps with Windows CE platforms... and many of the free apps there suffer from developer disinterest. WinCE software dies when the author becomes too busy with life/etc, while Linux and GPL software has a life all its own.
Some will complain about the N800's lack of CDMA/G3 data support, but this is GOOD -- really that is what your phone is for. Same thing with the keyboard... buy your OWN bluetooth keyboard if you want one. This was these 2 features do not bulk up the dimensions of the device.
If you want a "bigger" tablet, the Pepper Pad 3 seems interesting. If you want something that is truly portable, the Nokia N800 is the platform to beat now.
PS - the media player isn't horrible, but it suffers from limitations like any closed source media player. The media player has GOOD format support... many formats except no OGG support. The free 'Canola' media player offers a MythTV-like interface, touchscreen, and it plays just about anything you throw at it. Video performance on this is VERY good for a handheld.
Oh yeah, there's a webcamera built in and meeting software. Now we have to wait for Skype and GnomeMeeting so we can ditch the Nokia meeting app...
