iPad Air 2 Wi-Fi 128 GB
How an Ipad like a desktop? Can it run software like Microsoft office, Photoshop? Can it print to any printer? Can it receive and send emails and search the web?
The Best Buy stores in my town have the Microsoft Office for iPad in stock. I don't know about Photoshop. Go to the Apple App Store and type in a search for it. The iPad WILL print to most current printers which are WiFi/Bluetooth compatible. You will have to pair the iPad with the printer -- easy-peasy! If you don't know how to do this you can get Best Buy's "Geek Squad" for help in setting things up for you in your home.
Yes, you can certainly send and receive emails if you have access to the web via WiFi through some sort of internet service provider (ISP) using a modem and router. I would suggest you set up a WiFi system in your home through whatever provider you have access to. I do this thru my Cable TV provider Charter. Of course once you have a WiFi system in your home you can also search the web with the iPad.
What you CAN'T do is surf the web, send/receive emails on your iPad if you are trying to use it in a location where there is no WiFi "Hotspot" connection UNLESS you get a personal portable hotspot device from your wireless phone service carrier -- i.e. Verizon Wireless, AT&T, Sprint, etc. This device is a small portable "box" which you connect wirelessly to your iPad by "pairing" the two devices so they can communicate with each other. OR..if you have a "smart phone" you can use it as a WiFi hotspot (for a fee) to pair with your iPad.
The iPad can do many of the same functions that a laptop or desktop does, however for some functions it is a little more limited than a laptop/desktop. I highly recommend a bluetooth keyboard case for the iPad if you are going to do a lot of text entry and "typing" on it since the touch screen virtual "keyboard" is not so great for writing using such apps as Microsoft Office and for creating manuscripts, writing lots of text messages, emails, etc. Lots of people do it, but I much prefer using a keyboard for extensive text entry,
The iPad Air 2 WiFi is a great device. With 128 GB of storage you will be able to store lots of files, pictures, music and such on it. You will enjoy it. I suggest you speak with the knowledgeable sales folks at Best Buy. They will be able to answer all your questions and talk you through the process.
Good Luck!
