Today I got to see the LG Optimus 3D here at Mobile World Congress in Barcelona. I was impressed. Of course I cannot really capture it in a pic; but here it is anyway.
It really is 3D, which is amazing after a lifetime of 2D screens, and with no spectacles required.
The trick is that there are two screen images. When you look at the screen, your right eye gets a slightly different angle on the screen than your left eye. The technology uses that different angle to deliver a different image to each eye. At least, this is how it was explained to me.
There is also a dual-lens camera so you can take your own 3D pics and videos. The Optimus 3D has a 1GHz OMAP4 dual-core processor, and HDMI output for connection to high resolution external displays.
3D is cool and makes for some immersive games. But how much extra will customers be willing to pay for 3D on a Smartphone? Interesting question.
A big surprise here at Mobile World Congress in Barcelona: HTC’s new tablet, the HTC Flyer, comes with a stylus. “People can rediscover the natural act of writing,” says the press release.
My first reaction is that this a mistake. I have had tablets with pens before, and while I like the ability to take notes, I also find the pen a nuisance. They are awkward in confined spaces like an economy seat in an aeroplane, and expensive to lose. HTC’s pen is battery powered, so I suppose you could also have the annoyance of a pen that runs out of juice. HTC’s stylus does not clip into a bay on the device, but does have a dedicated pocket in the case.
On the plus side, you can write, draw and annotate content using the pen, which has a variety of settings for colour and tip. For some tasks, a pen is the ideal implement.
The device does have other attractions. The pre-release devices have Android 2.4, but HTC says it may well run Android 3.0 “Honeycomb”, which is designed for tablets, by the time it is launched in Q2 2011 or soon after. It has a 1.5Ghz Qualcomm Snapdragon chipset; 7” screen; 1024 x 600 resolution; 1GB RAM and 32GB storage, expandable with micro SD cards. Battery is said provide 4 hours of video playback, which sounds less than ideal. HTC will also offer a video download service “HTC Watch”.
A feature which will be familiar to OneNote users is called Timemark. This lets you take notes which synch to an audio recording, so tapping a word in your notes takes you to that point in the audio. Notes also synchronize with Evernote, a cloud-based note synchronization service.
Viewsonic has announced the ViewPad 10 Pro, a 10” tablet that runs both Microsoft Windows 7 and Google Android 2.2.
I saw the ViewPad 10 Pro briefly this morning here at Mobile World Congress. Specs include Intel Oak Trail chipset, 2GB RAM, 32GB storage, and front-facing camera for conferencing.
The big appeal of the ViewPad 10 Pro, successor to the ViewPad 10, is that it runs Android as well as Windows. Just tap a button, and Android appears in place of Windows.
Sounds good; but as Viewsonic explained how this works I became doubtful. Apparently Android runs in a virtual machine on top of Windows. I have nothing against virtualization; but this approach does suggest some compromises in terms of Android performance and efficiency. No matter how clever Viewsonic has been in its implementation, some resources will still be devoted to Windows during an Android session and battery life will be less good than it might be.
I can see more sense in running Android first, for the sake of its speed and efficiency on low-power hardware, and Windows in virtualization for when you need to dip into Excel or some other Windows application.
The upside of this approach is that you can switch between the two without having to to do a hard reboot.
Viewsonic says you will be able to get one of these in your hands around May 2011.
The BBC has announced apps for Android and iPad, sparking a bad-tempered discussion (see the comments) in which users complain about two things:
1. The requirement for Flash 10.1 or higher on Android, which limits it to Android 2.2
2. The fact that catch-up viewing is only available on-demand, as on the Web, and not for offline viewing.
Both are interesting points, but to my mind the first is the biggest deal. As one of the commenters observes:
As people have pointed out you can use the web interface to watch so using up valuable memory on a phone for an app that does the same thing essentially is not very useful!
By contrast, the ability to download two or three programmes for viewing on the train or plane would be a huge feature. Downloaded video is also more robust even when you are online, thanks to the variability of typical wifi or 3G connections.
Storage is an issue, but not such a bad one now that cards with 16GB or more are commonplace. My HTC Desire currently has 14GB free on the storage card – plenty for a few videos in quality suitable for a tiny screen.
Apple’s devices do not support add-on storage cards, but even the cheapest iPhone 4 has 16GB of storage, as does the iPad.
When a friend showed me their two-year old Toshiba laptop that had suddenly developed a fault, I was not optimistic. The screen was showing a blur of horizontal lines and you could not even make out the image Windows was trying to show. Likely a faulty screen, but is it an economical repair?
I verified that it was only the screen that was faulty by connecting to an external display, which worked fine. Then I took a closer look at the faulty screen. I noticed that if I pressed the upper left screen trim, it started working. Release the pressure, and the lines reappeared. That seemed to me a good sign.
The last time I tangled with a laptop screen was a few years back. At that time, with the models I looked at, you had to remove the keyboard and numerous other parts to get at the screen; but it seems that it is simpler now. I removed the battery and power, and then unscrewed four screws in the screen trim, following which I could pop off the screen trim by gently prising it away. This enabled me to look at the back of the screen, where the model number was shown. It was a Samsung LCD screen. I figured it would probably be cheaper to search for the Samsung part, rather than finding out what Toshiba would charge for a replacement.
It turns out that a new screen is available for around £75-£85 from sites like this one. Probably worth it for a decent laptop just a couple of years old. The following video, from the same site, shows what is typically involved – though be warned, your particular laptop may be different.
Still, I was wondering if it needed a new screen at all. It might just be a loose connection, since I could fix it with finger pressure. I removed the screen completely by unscrewing it from its bracket, so I could easily get at the VGA connection. I lifted a small piece of tape and removed the connector. Then I reinserted it, pressing it home firmly. Reassembled the screen, replaced the battery and turned on.
Since then, no fault. Who knows, it may recur, but for nothing more than a short time with a screwdriver I am glad to have extended the life of this particular laptop.
PS If you try the above, you do so at your own risk. It is easy to do further damage, so if in doubt consult a specialist.
