Q. When are companies going to start writing applications for tablet computers other than the iPad? I own a Pandigital tablet, and when I try to download apps, Im told theyre either for the iPad or iPhone.
Oro Valley, Ariz.
You can expect more apps for non-Apple tablet computers when those devices gain more market share. How soon, or if, that will happen is anyones guess.
People who write apps are motivated by the revenue theyre likely to get. They can maximize that revenue by focusing on the tablet computer that is owned by the largest number of people.
Right now, the best opportunity for app writers is the iPad, which in the first three months of 2012 accounted for 68 percent of the 17.4 million tablet computers sold worldwide, according to market research firm IDC. The iPads chief competitors, in order of market share, are tablets made by Samsung, Amazon, Lenovo and Barnes & Noble. Pandigital is further down the list.
Q. I recently bought a Kindle Fire tablet computer, and Im disappointed that it cannot be read in the sunshine as other Kindle devices can. Is there anything I can do to make the screen more readable outdoors, such as buying an anti-glare screen protector?
Mary Jo Ready, Shoreview, Minn.
An anti-glare protector wont help. The issue is that your Kindle Fires LCD, or liquid crystal display, screen is lit from inside, but isnt bright enough to compete with sunlight. Your only outdoor options are to raise the screen brightness and find some shade. A video that explains how to adjust screen brightness can be found on Amazons help pages, at http://www.tinyurl.com/7289vlo.
Q. My Windows task bar was always at the bottom of my screen, but the other day it went to the top for some reason. How can I get it back to the bottom of the screen?
Kathleen Gignac, Bartow, Fla.
The task bar can be dragged to a new location using your mouse. Left-click a blank space on the task bar and, while holding down the mouse button, drag the bar to the bottom of the screen.
You can skip this manual process if you are using Windows XP or Windows Vista. Just go to http://www.tinyurl.com/c7qwp8 and click the automatic fix it button. That will return the task bar to its default position at the bottom of the screen.
If you have problems with either of these techniques, the task bar may have become locked in its current position. There are directions on the same Web page that explain how to unlock the tool bars location so it can be moved.
