iPad WiFi Versus iPad 3G - Five Major Differences Between iPad WiFi and iPad 3G

So, what's the difference between an iPad with WiFi and an iPad with 3G plus WiFi. It's a question that seems to come up frequently, so I thought it would be worth finding out some answers to the question.
I've found five major differences between the two models and keep on looking for more. Here are the five differences:
Number 1: Limited connectivity vs. Extensive connectivity. With the iPad WiFi your connectivity to the internet is limited to areas where you can access the web via WiFi. With the 3G version of the iPad you can connect both via WiFi or the 3G cellular network. That means it should have connectivity anywhere you get cell phone coverage. To get the same coverage with the WiFi version you would need a portable WiFi, like Verizon's MiFi or some of the smart phones that can act like a WiFi.
Number 2: You Pay for More Connectivity. The 3G iPad costs more to buy. At the time I write this, the difference is about $130 in the US. To use the 3G wireless service you need to have a wireless data plan with you carrier. In the US, AT&T provides data plans for a price. To start they had a $14.99 per month data plan with 250MB of data included and a $30 per month "unlimited" plan. The unlimited plan was discontinued pretty quickly and now you can get 2G of data for $25 per month.
Number 3: iPad with 3G also has built in GPS service. The WiFi version can do some triangulation; you need a 3G iPad to get a really accurate location fix.
Number 4: Some small physical differences. On the back of the 3G iPad there is a black plastic section that enables the iPad to get a better connection to the wireless network. The 3G version also has a door on the side for you to insert the Micro SIM card. These differences are probably not that big a deal given that you will probably want to use an iPad cover to protect your iPad.
Number 5: Shorter Battery Life for the 3G. Using the 3G network chews up more battery. From what I have read it cuts battery life from about 10 hours down to between 7 and 8 hours. Not bad, but it does count at the end of a long day.
So to sum it up, if you are just using the iPad around the house, get the WiFi version and if you need to use it out in the field you are probably better off getting the 3G version of the iPad.

iPad And iPhone Apps - The Similarities And Differences

People who design an iPhone app know the similarities and differences between the iPhone and the iPad and their impact on the apps used in these two very popular and smart devices. When the iPad was first introduced to the market, Apple let people know that their iPhone apps can perfectly be used in iPads and it was true. However, as time passed and new apps were created and used, more and more of those applications became exclusive to one or the other of the devices.
First let us look at the similarities and differences between the iPhone and the iPad and how they affect the design of iPhone apps.
The iPhone is used to make phone calls or video calls on some models, send text and email messages, read books on it, play music and videos, surf the Internet and take photos. The iPad is used mainly for browsing online, reading books, and playing multimedia files.
So basically, the iPad can do all the things that the iPhone does except make calls and send text messages. However, some iPad apps do allow us to send texts. So what are their differences?
The iPad is a much larger device and has a bigger touchscreen than the iPhone. Because of its smaller size, the iPhone is primarily used to make phone calls. On the other hand the iPad serves as a PC or notebook. The docking device of one of the models has a physical keyboard which when attached to the tablet, converts it into a laptop or notebook. Very cool!
If you want to create an app for the two devices the difference in size is a key factor.
Today, you don't want to use an app you're using in your iPhone in your iPad or vice versa. It may work, but not as perfectly as in the device it was originally created for. The people who create iPad apps have taken advantage of the larger touchscreen of the tablet. iPad apps when downloaded on the iPhone do not look as great. The 'shrinking' of the app renders it unreadable. The reverse is true of the iPhone app. However, the pictures and text of the magazine and newspaper apps won't fit on the smaller touchscreen of the iPhone. And the iPhone apps downloaded on the iPad device, suffer a loss of quality. The graphics are enlarged and they become pixellated and blurry.
To fix these issues, some people who design iPhone apps have created two versions for the devices. All the user has to do is to download the correct one on his device and enjoy its graphics and functionality.
