Here's my take on the ipad2. As others have said, there are some features that some people may use more than others but if you want it to do several things but not have to use a laptop/computer(or lug one around), it might be a good choice. Ultimately, you will need a dedicated laptop/computer to do any serious typing and or document work. Not that it cannot be done on the ipad, it's just not as fast or convenient. Kinda like writing a message on a DMDG/KL43 compared to a normal keyboard.
From a work/business standpoint where some people might have issues is the ability to synch up with work mail and or calendars that are MS based. There might be an app for that but I am not aware of one and or the system admin may not know how or want to allow your Ipad/Mac to interface with the network.
There is also no MS office package for ipad, there are apps that handle MS documents though. These apps can be purchased from free to around $40 bucks. The ones you pay for tend to work better but again, they are not like full blown MS applications. Meaning you may not be able to do something in an Excel sheet that you could do on your PC with MS office on it. However, you will be able to open, look at, make changes (no major muscle movements should be expected) and save documents that were generated in the MS format. You may have to search and play with a few of the apps to find out which one works best for you and your needs. The reviews of the apps usually give you a clue about the app but don't be surprised to see people give a negative or low score to an app because they couldn't lock a field in excel and do other major muscle movements like one would on a laptop computer. There is one that I would recommend but it's name escapes me at the moment, it costs a few more dollars but it seems to work the best out of all that I have encountered.
Where some people encounter a bottle neck be it pictures or documents is with the ability to send them back to someone or to themselves (mac/PC). The free and easy work around is to use Dropbox on all of your platforms ( phone, ipad,home computer and work computer if allowed) and place the important or most used documents in your dropbox.
For pictures, there is an app called photosynch that allows you to wirelessly send photos from your phone to an ipad and or computer and it works in either direction. I used it to send around 30 plus camera photos to the ipad and it took less time than it does when I transfer photos from the phone into my Mac with the cable. It's a pretty good app if you want to share pictures or move them quickly from one platform to another.
For web browsing, I would recommend Atomic web browser. I believe it is free and it allows you to have multiple tabs open, much like you can do in Safari on a Mac, something you can't do in the ipad version of Safari.
Like anything else, it's a tool that if you use it and become familiar with it, it will seem worthwhile and you'll find yourself using it more and more. If you expect it to work exactly like a laptop/desktop you will be disappointed in some areas.
For those looking for a good knuckle dragger proof cover for their ipad, you should check this one out, it's probably the equivalent of an Otter Box for your ipad.
