my wife got one last night. the 64GB wifi+3g. so far, it's a lot better than i expected. i was VERY weary of it at first as a lame laptop wanna-be.
she was impatient and bought the 3G even though we may not get it (i may be getting the palm pre plus through verizon and they have free mobile hotspot right now). we got the bluetooth keyboard as well and it works very well.
the learning curve isn't too bad. but my wife loves it. i'm not completely hooked, but i'll end up using it for my grad school studies this fall.
the Pages app works really well and is pretty seamless with our Mac MS Word. all the other things are for fun. it'll be a lot nicer to watch movies and such than on an iphone or other smartphone device.
it wasn't cheap for sure. but i think it'll be worth it in the long run.
