Honestly, I was in the same boat. I have a macbook, Own several generations of touches, and don't plan on using a tablet/touchscreen besides my phone (blackberry and iphone, just happened that way-- im not ballin or retardedly rich...one of the phone's contract is gonna end soon and im gonna end it) so i figured why the eff would i need an oversized ipad.
I dissed the hell out of it when the ipad 1 was first announced btw.
my buddy left his Hp tablet running android at my place for a week cause he forgot it here.. since it was there i just played with it and man, ive been converted ever since. I'd wake up in the morning and get out of bed an hour or hour half later
I'd check email, check the news (even more frequently than I already read them) and just browse the internet. I didnt really touch games (he didn't really have many and i was too lazy to download)
But it's just the simplicity, ease, portability and the fact that i can, do all that on a light tablet that i did. Sure i had my macbook (upgraded the **** out of it, so its blazing fast) but it just wasn't the same. If i wanted to do serious browsing and typing i'd pull out my mac, but everything I needed to do regularly, was right there on that tablet.
Everytime i wanted to google something, check something, i went with the tablet. It's kinda like having my 51" at the foot of my bed, and finally having a remote to change the channel. May be an overly exaggerated poor analogy but u get the idea. This was my personal experience, the same guy that was a windows fanboy, the same guy that hated the concept of tablets, now can't live without his apple product and has an ipad 3 on the way. YMMV, just like any product, its not ment for everyone. 14 day returns no hassle ftw
