I drank the kool-aid on Friday and bought the 16gb wifi iPad. I'd been flirting with the idea for a while and went in to a Best Buy to have a better look at them. From the moment I picked it up I was hooked. An amazing device.
I've had an iPod touch for a few years and really liked it but was not a fan of reading entire novels on it. The iPad is much better suited to that with it's "slightly" bigger screen. The iBook app is a pleasure to use for both epub and pdf formats although I do prefer Stanza in some situations.
I also have a kobo reader which is nice for on the go reading and weighs in at just over 200gm (~ 2/3 less than the iPad).
Haven't been a huge fan of graphic novels (aka comic books) until now but the way the iPad renders them is amazing.
My only complaint is that for $500+ they could have put a small office suite on the device instead of geting us to pay $10 for iNotes etc. Oh and an SD slot would be nice...
The fun of owning it/using does take me back to my own C-64 days...my we've come a long way...
