Neither of those things are problems.
The battery "issue" is actually intelligent battery management. In order not to prematurely break the battery, Apple has—for years!—built charging circuitry that will load the battery, and then gently allow it to deplete just a couple of percent, and then gently re-charge, etc., to keep the electrons moving.
The iPad reports "100%" at the lowest point the charging electronics will let it discharge while on external power, just so we don't have a bunch of people whining about how they left the iPad on charge the entire night, and it's still only at 97% and how it's all broken and Apple needs to fix it.
The third "issue" was that some stupid dolt used up his entire data quota in just two or three days while watching video via LTE. Wow DUH. Using a fast data connection to download masses of data will use up your data allotment. Only a complete idiot would think otherwise, but the "press" jumped on it (albeit briefly).
Nice piss-take on the supposed iPad "issues" by the wonderful Macalope:
There are no "issues" with the iPad, but "news" sites and "journalists" are desperately fabricating and/or jumping on ANYTHING that might make it look bad, just to garner page hits.
Feel free to wait, but it's not terribly likely that Apple will ever "fix" things that aren't broken, or that are specifically designed to work that way.
