Which iPad to buy?
Q. I want to buy an iPad, but I see there are a bunch of different models. Which one is right for me? How much storage do I need?
A. The big decision you have to make is whether you want an iPad with Retina display, iPad Mini or iPad 2. I would pick the Mini if you want a one-handed gadget thatís great for gaming or browsing. Pick the Retina display iPad if you want to watch movies, since it has the best screen. If you just want a cheap, quality tablet, stick with the iPad 2. As for storage, the smaller 16 gigabyte version should be enough for most people. If you really need more storage, look into iCloud and other free cloud storage options.
Improve battery life
Q. My Android tablet is running out of juice too quickly. Is there any way I can increase its battery life like I can with my smartphone?
A. Tablets and smartphones actually share many battery-draining features. Start by changing the tabletís screen timeout and brightness. You can find this by to Settings>>Display on your Android. iPad owners should go to Settings>>General>>Auto-Lock to change the screen timeout and Settings>>Brightness to change brightness. Using your tablet in airplane mode is smart when you donít need Wi-Fi or other data connections. Those connections drain the battery fast. To find airplane mode, go to Settings>>Wireless & Networks on Androids and Settings>>Airplane mode on iPad. Finally, Android tablet batteries can benefit greatly from a task-killing app like Advanced Task Killer, especially if you run power-hungry apps.
Buy discounted gift cards online
Q. My grandkids love gift cards for Christmas and I heard some sites sell discounted ones. What are some of these sites?
A. There are actually dozens of sites to choose from where you can buy gift cards from other people. GiftCardGranny and Plastic Jungle are two of my favorite because you can sell cards on them, too. If youíre a Samís Club or Costco member, you can find discounted gift cards there as well. Those stores usually sell cards at a 15 to 20 percent discount for restaurants and theaters - which make good gifts. Donít forget to follow your favorite stores on Twitter and Facebook, too. Stores often pass out exclusive Web deals and have gift card giveaways on social media. When you buy, just make sure the card doesnít have an expiration date.
Are ereaders still good buys?
Q. I was debating buying an ereader because I like to read on planes and during travel, but I saw that there are tablets that are almost the same price. Should I buy one of those instead?
A. New 7-inch tablets like the Nexus 7 are close to high-end ereaders in price, but if you just want to read, stick with the ereader. Extended reading on an ereader will hurt your eyes less and battery life on ereaders blows tablets away. As for which to buy, I would stick with Amazonís Kindle Paperwhite (starts at $119 for an ad-supported version) if you want an ereader with a fantastic screen and features like email and an experimental Web browser. The Nook Simple Touch with Glowlight ($119) is less expensive without ads, but doesnít include some of those more advanced features.
Remove Facebook apps
Q. I connected my Twitter account to Facebook because I thought it would let me manage my Twitter profile on Facebook. It doesnít, so now I want to disconnect it. How do I do it?
A. A good tool to manage both accounts at once is TweetDeck. To disconnect the Twitter app, or any app, click the upside-down triangle in the right corner of your Facebook profile and choose Privacy Settings. In the Apps and Websites menu, click Edit Settings in the Apps You Use section to bring up a full list of apps connected to your profile. You can easily block specific apps. If you want to block all apps, click Turn off all apps. If you change your mind and want to bring an app back, you can do that in the Blocked People and Apps section of your privacy settings.
