The thing is the ipad is what most people want in a computer.. it's really easy to use and isn't complicated.
You can browse the web, listen to music, download apps from a single on device store, read ebooks/audiobooks etc.
Naysayers don't really have it right. If your a complete nerd you might want something with more power and control (that will probably break and require you to fix it).
But if your an average person, that wants to get to work and use the web, the ipad is perfect.
Personally though I would save some cash and get a refurbished ipad 1 instead. They are not that different.
You could get a basic ipad wifi for just $399 ($100 less than apples current basic ipad):

Or you could opt for a 32GB/ 3g ipad for $519 ($210 less than apple for a 32gb ipad!)

The 3g ipad is nice if your an internet addict because you can use the internet anywhere you have cell phone coverage, vs just wifi hotspots.
Also, it's slightly easier for non geeks since there is nothing to setup at home, since the internet is ready to go vs having to setup your own wireless connection.
But.. it costs with a monthly data plan.
