A few questions about common "issues" before buying New iPad

I am hoping to pick up the new iPad in the next few weeks, however I have read up on some issues which I'd like some information on.

I have been using my GF's iPad 2 a lot and I really love it, however I am dead set on buying the new one, I have become pretty resolution-spoilt by the awesome screen on the 4S and this is the primary factor in wanting this new model.

With the following concerns, assuming that an iPad that I may buy might have one or more of them, could you please inform me of: any currently known official or unofficial fix, if the problem could most likely be resolved in an update or if it is likely that since the problem came to light that the later runs to be built were adjusted to avoid the problem? Thanks.

OK- first up, the bad wifi problem that people have. This is the biggest concern to me, as I use wifi a lot and won't have access to 4G, and only occasionaly access to 3G.

Secondly, the heating... OK this is not a deal breaker, I understand that it isn't a real problem however if it could be solved so that it runs almost as cool as the 2 that would be great.

Thirdly, charge times and the extra hour over 100%... Again I do realise that these aren't so much issues as just the way that it works, however I would hope that now lots of people have complained, an update would adjust the display to be more accurate, to say 100% only when it has fully charged, purely because I would rather know... Or perhaps have 100% change colour on absolute 100%. The other thing, 7 hours charging, is there a more powerful adaptor that 1: reduces the charge time, and 2: if you are using a powerdrinking app while charging, will actualy continue charging rather than just slowing the battery drain (I read that some apps will keep draining battery while on charge).

finaly, I have read about screen hue problems, this wont be too much of a problem, as I will be able to check this in store to be sure that the screen is nice, colour balanced and free of dead pixels, I will compare it to my GFs iPad 2 and also the iPhone 4, because I know that the iPad 2 is supposed to look a little more blue to give it a cold feel, while the new model and the iPhone 4S have a slightly yellowed screen for warmth, it's just that lots of people have complained about theres' being too yellow.

Thanks very much for any useful info on this.
