I have had zero problems with the iPad. It is ridiculously fast. I have had no problems with the WiFi at home or in public.
I can do the things I usually do on the laptop, surf the net, e-mail, watch or listen to media etc quite well on the iPad. In fact, it's superior to my laptop.
I simply love reading my eBooks. The NYT, USA Today, NPR are great. I can "bypass" using the web browser. And, it's just the tip of the iceberg.
I think a lot of folks just don't get it. That's fine. They can wait for the Slate, which will be a clunky and not offer anything new. Do the PC folks really expect Apple to put a software designed for keyboard and mouse into a device designed for multitouch? What would gained other than the loss of a keyboard? Big whoop.
Yes, I wish Apple had put a front facing camera for video chat and I wish the software already supported multitasking but it's will get thiere.. I really don't care about printing from the iPad. I have little use for printing anyway. I am not using this for work.
I really don't care that much about filing either as long as there is a way to store it in a cloud.
