If you've owned an Android phone, there's no reason why you should claim an iPad is more superior than an Android tablet. Sure, performance wise and longevity, the iPad may outlast and outperform a Samsung tablet 5 years from now, but the iPad is just as restricted as the iPhone. You're only allowed to download apps from the App store. You can't really customize how your tablet looks and you're stuck with the bland vanilla iPad design. You're restricted with the amount of storage on your iPad as there is no microSD slot. The only difference between an Android tablet and an iPad is basically user preference. Both offer great features and both have their negatives. It comes down to what you're REALLY using the tablet for.
As a side note, I have (and am currently using it as I type) a MacBook Pro 13 inch from early 2011 and it's still going strong to this day. Not as fast as it used to be initially but it's only a few seconds delay on loading up applications and the Finder window. It's a shame that when Steve Jobs passed away, the intuitiveness and creativity that was Apple also died with it and started a downward trend despite what the sales and profits show.
