Standardize computer access in hotels, and vnc everywhere
Hotels are now commonly sporting flat widescreen TVs, usually LCD HDTVs at the 720p resolution, which is 1280 x 720 or similar. Some of these TVs have VGA ports or HDMI (DVI) ports, or they have HDTV analog component video (which is found on some laptops but not too many.) While 720p resolution is not as good as the screens on many laptops, it makes a world of difference on a PDA. As our phone/PDA devices become more like the iPhone, it would be very interesting to see hotels guarantee that their room offers the combination of:
- A bluetooth keyboard (with USB and mini-USB as a backup)
- A similar optical mouse
- A means to get video into the HDTV
- Of course, wireless internet
- Our dreamed of universal DC power jack (or possibly inductive charging.)
Tiny devices like the iPhone won't sport VGA or even component video out 7 pin connectors, though they might do HDMI. It's also not out of the question to go a step further and do a remote screen protocol like VNC over the wireless ethernet or bluetooth.
This would engender a world where you carry a tiny device like the iPhone, which is all touchscreen for when you are using it in the mobile environment. However, when you sit down in your hotel room (or a few other places) you could use it like a full computer with a full screen and keyboard. (There are also quite compact real-key bluetooth keyboards and mice which travelers could also bring. Indeed, since the iPhone depends on a multitouch interface, an ordinary mouse might not be enough for it, but you could always use its screen for such pointing, effectively using the device as the touchpad.)
Such stations need not simply be in hotels. Smaller displays (which are now quite cheap) could also be present at workstations on conference tables or meeting rooms, or even for rent in public. Of course rental PCs in public are very common at internet cafes and airport kiosks, but using our own device is more tuned to our needs and more secure (though using a rented keyboard presents security risks.)
One could even imagine stations like these randomly scattered around cities behind walls. Many retailers today are putting HDTV flat panels in their windows instead of signs, and this will become a more popular trend. Imagine being able to borrow (for free or for a rental fee) such screens for a short time to do a serious round of web surfing on your portable device with high resolution, and local wifi bandwidth. Such a screen could not provide you with a keyboard or mouse easily, but the surfing experience would be much better than the typical mobile device surfing experience, even the iPhone model of seeing a blurry, full-size web page and using multitouch to zoom in on the relevant parts. Using a protocol like vnc could provide a good surfing experience for pedestrians.
Cars are also more commonly becoming equipped with screens, and they are another place we like to do mobile surfing. While the car's computer should let you surf directly, there is merit in being able to use that screen as a temporary large screen for one's mobile device.
Until we either get really good VR glasses or bright tiny projectors, screen size is going to be an issue in mobile devices. A world full of larger screens that can be grabbed for a few minutes use may be a good answer.
