For a few bucks more than a Kindle Fire or an 8Gb Nook Tablet, this is a no-brainer. Cons are its lack of microUSB for syncing and charging (uses the expensive and hard to find proprietary Samsung Galaxy Tab latching connector). Also, it's got about 5.3Gb free for internal app storage. Since it's running ICS, that means no apps stored on SD, so you will run out of internal room very quickly if you want to load up any big Gameloft or EA-style 3D games which can run up to 800Mb apiece. For casual gaming, web browsing or e-book usage it's perfect.
The older Galaxy Plus 7.0 has a better screen, camera, CPU/GPU and 2x the storage but it's getting hard to find and costs a lot more and is still running Honeycomb and is still only 1024x600.
