This is just something for the house, something that can be taken from room to room. Or something to take when travelling, its easier to take that over the 17" laptop.
Not trying to start a fanboy thread, there is already one for that. I just don't know the advantages of each one.
You're going to have a hard time finding objective opinions in this subject, your best bet is probably to play around with them and see what you like best.
In my opinion, Apple is the only one that has made a solid impact on the tablet realm. The competition is simply trying to figure out what they can do to differentiate themselves without actually thinking of how to make a better end product for the consumer. Look at Samsung, just checked and they have a 7", a 9", a 10" Tab, plus they're coming out with a 10" Note with a stylus (yay?). Pretty obvious they're just releasing products hoping that something catches on.
I also have a few fundamental issues with Android. Most importantly is the upgrade process. When Google releases a new version of Android, unless you have a Nexus product, you have to wait for the maker of your product to customize the new version and release it to you. With a big risk that they won't update it at all and then you're stuck using older software. Ice Cream Sandwich has been out for five months now and a lot of the older products still do not have support for it. Here's a stat,
http://9to5google.com/2012/03/06/ic...devices-android-app-size-limit-raised-to-4gb/, where only 1.6% of Android products used ICS. In comparison, IOS5 is at around 75% adoption last I checked. That's great for consumers on two fronts, they get the latest software without hassle, but also developers only need to focus on creating apps for one version of ios.
Also the Android guys seem to have forgotten that some people like myself do like to use their tablets in portrait mode. Apple's 4:3 screen ratio makes it a perfect compromise for portrait and landscape use. Most of the Android tablets use a 16:10 or 16:9 screen ratio, great if your primary usage is watching videos, ****** if you use portrait mode for reading.
