The Samsung Galaxy Tab 10.1 is a state-of-the-art tablet. As Samsung?s second entry into this market and first Honeycomb tablet, it?s an impressive device and a good platform to build on.
Whether it?s for you will depend mostly on your application and connectivity needs. Yes, Apple has many more apps, but it all comes down to which ones you need or want. The Tab also is more versatile in media formats it supports, which should give pause to those who are buying it mostly as an entertainment device.
If you?re a road warrior buying it as a laptop alternative, the Tab has the edge on usability when it comes to text entry, if you can find the apps you need for work. But the basic set of calendar, email, contacts, browser and QuickOffice (maybe augmented by Google Apps, Evernote or similar options) will make the Tab a good choice for many road warriors, provided that Wi-Fi is going to do it for them.
If you?re an Apple loyalist, iPad?s common features with the iPhone and general compatibility with the Apple world likely outweigh any minor feature advantages the Tab has. If you?re a Windows or Linux person, not so much. iTunes on Windows is not the greatest and makes managing the iPad cumbersome compared to the Tab.
Lastly, if you?re going to want to use this often where Wi-Fi is not available, forget it.
Back to my original thought: if I was buying my first tablet today, would I go for the iPad 2 or the Tab? I?d have to say the iPad 2, despite my preference for some of the ergonomics of the Tab. The app advantage tilts it for me.
