8 Tablets for Business: the Pros and ConsAs more companies offer a wider variety of tablets, it might be time to go shopping for one for your small business.

Tablet computersare in high demand -- from Apple's popular iPad and much-rumored iPad mini, to Google's smaller but powerful Nexus 7 and Microsoft's forthcoming Surface.

But as the popularity of the Kindle Fire proves, tablets are not one-size-fits-all. For business users, your choice can depend on how you plan to use a tablet -- making presentations, processing transactions or reading documents. You should also take into account your preferredmobileoperating system, availableappsand the kind of connectivity you'll need.

Here's our guide to eight of the best existing and soon-to-arrive tablets:

Apple iPad: 3rd generation

In March,Applelaunched the third-generationiPad, notable mainly for itshigh-resolution Retina display, more powerful five-megapixel camera and optional 4G wireless network connectivity.

Pros:Several iOS business apps have versions designed specifically for the iPad, including task-management toolOmniFocusandMicrosoft Office.

Cons:But many iOS apps for services popular with small-business users, such asFreshbooksandGoToMeeting, are still designed only with the iPhone in mind. This means using such apps on an iPad is like having a giant iPhone, and many iPad users find them unwieldy.

Price:From $499 (16 GB, Wi-Fi only) to $830 (64GB and 4G with AT&T or Verizon service). As with any tablet, you either have to pay for a new tablet data plan or add the device to an existing plan. Price vary depending on the carrier.

Nexus 7

Manufactured for Google (Android) by Asus, theNexus 7tablet, was introduced in the U.S. this summer. It has a display measuring only 7 inches diagonally, compared to the 9.7-inch iPad display.

Pros:Smaller tablets fit more comfortably into pockets or purses and tend to be more convenient to hold with one hand. So far, the Nexus 7 is the only tablet sporting the latest version of the Android operating system, called "Jellybean." It will be among the first to receive Android system updates pushed directly from Google and not from wireless carriers or device manufacturers.

Cons:So far, the Nexus 7 is Wi-Fi only, and the maximum available storage is 16 GB. There isn't a sizable selection of Android apps optimized for this device yet. But because it's a relatively small tablet, using apps designed for Android smartphones may be acceptable.

Price:$199 (8GB) or $249 (16GB).

Samsung Galaxy Tab models

One of the first Android tablets to hit the market, theGalaxy Tabwas released in the U.S. in late 2010. Currently, there are three main products in the Galaxy Tab family.

Pros:On the large side, Samsung's full-size Galaxy Note tablet features a 10.1-inch display and comes with an "S-Pen" stylus option, which can be useful if you sometimes prefer writing or drawing on your tablet in a paper-like fashion.

If you prefer a smaller tablet or 4G wireless connectivity, Samsung offers the seven-inch Galaxy Tab 7.0 and it's counterpart, the 7.0 Plus. In between, size-wise, is the Galaxy Tab 7.7.

Cons:Galaxy Tab products come with the "Ice Cream Sandwich" version of Android, as modified by Samsung. This means that updates to Jellybean and future Android "flavors" will lag behind Nexus tablets,perhaps by many months.

Also, all 10.1-inch Samsung Galaxy tablet models are Wi-Fi only.

Prices:星系注意平板范围从499美元(16 gb)$549 (32GB). The 10.1-inch version of Samsung's Galaxy Tab 2 starts at $399 (16GB). The Galaxy Tab 7.0 and 7.0 Plus cost about $250 (16GB, 4G) from carriers. The Wi-Fi only models cost up to $100 more. The Galaxy Tab 7.7 is available only from Verizon, so it includes 4G access, and starts at $279 (16GB).

Samsung Galaxy Note hybrid phone/tablet

If you'd rather not carry two mobile devices, this hybrid phone/tablet may be right for your business. Samsung launched theGalaxy Notea year ago.

Pros:It's like two mobile devices consolidated into one. Also, it features Samsung's S-Pen stylus, which reviewers have praised for its precision and responsiveness. And it includes an eight-megapixel front-facing camera.

Cons:At 5.3 inches, the display is large for a phone, but small for a tablet. Some users find this awkward. The Galaxy Note may come with Android Ice Cream Sandwich installed but, depending on carrier or retailer inventory, some devices may be shipped running Gingerbread -- a much older version of Android.

Price:Available in the U.S. via AT&T starting at $199 (with a two-year service contract) or $599 (no contract), or from T-Mobile starting at $249 with a two-year contract or $699 (no contract).

TheAsus Transformer Pad Infinityfeatures a high-resolution 10.1-inch display and up to 64 GB of memory, and it comes with Android Ice Cream Sandwich.

Cons:This tablet is Wi-Fi and Bluetooth only.

Price:About $480 (32GB) and $580 (64 GB).

Microsoft Surface tablets

Reportedlygoing on saleOct. 26, theSurfacerepresents Microsoft's first serious foray into the tablet market.

Pros:According to Microsoft, these tablets will featurethe new Windows 8 operating systemdesigned to run on both computers and mobile devices.

The base Surface model will run a slightly modified version of this operating system (Windows RT) and will be available in 32 and 64 GB versions. The Surface Pro will run straight Windows 8 and come in 64 and 128 GB versions.

They also will feature a 10.6-inch HD display and a molded magnesium casing, which could make them look and feel sleeker than most Android tablets.

Cons:Windows 8 features a new tile-based user interface called "Metro." Users who are accustomed to previous versions of Windows may find it perplexing. Windows apps will need to be radically redesigned to accommodate this operating system, and will probably require further optimization for the Surface.

Price:Microsoft CEO Steve Ballmer has hinted thatprices could rangefrom $300 to $800.

HP ElitePad

Microsoft won't be the only company selling Windows 8 tablets. In January, HP expects to launch itsElitePad, a 10.1-inch tablet intended primarily for business users.

Pros:It will come running the Windows 8 operating system, but reportedly it also will beable to run Windows 7 or XP. Up to 64 GB of storage will be available.

This device is meant to be durable, with a more rugged casing than most tablets have. It also comes with security software installed. Accessories will include a jacket with extra battery, stylus and docking station.

Cons:It will face the same issues with the new Windows 8 user interface as the Microsoft tablet. Its security measures and some other features may be overkill for most small-business users.

Price:Not announced yet, but expect the ElitePad to be costlier than most comparable tablets.

Apple iPad mini

Apple isexpected to announcea smaller and less expensive iPad model as early as Oct. 23.

Pros:In September,leaked imagesof a purported iPad mini showed a 7.85-inch display, compared to the 9.7-inch display on the standard iPad. At this size, iPhone apps that are unwieldy to use on a full-size iPad may seem better.

The iPad mini would probably offer 3G or 4G network access, in addition to Wi-Fi.

Cons:Apple will need to keep the price range for this product competitively low, and that will entail tradeoffs. Unlike the standard iPad, an iPad mini would be unlikely to have a Retina display. And the base model may come with only 8GB of memory.

Price:If rumors prove true, the iPad mini will most likely be priced to be competitive with Amazon's Kindle Fire HD, which starts at $199.
