iPad 3  or Samsung Galaxy Note 10.1? 
And, why?

 Note 10.1 
Multi tasking 
S Pen
Samsung premium suit 
Expandable memory
front speakers
Inbuilt remote
This is best tab in market. 

 Thanks... So, none of them are in iPad3. 
What features that are in iPad3 but they don't exist in Galaxy note tablet?

 I would suggest you to wait for few more months because they will be introducing a new ipad if not then certainly go with the ipad 3. 

reason:

same as above by pepsi ji.

If you are gona get the ipad then get the lastest ipad. The ipad 2 is only a hundred dollar less but it lacks the new retina display which i think is one of the most important aspect of using the ipad. So definetly go with the latest one. 

Apparently the ipad3 has been discontinued so ipad4 is the new ipad3!

 I meant the latest iPad. I am looking for maximum of great features. Money is not an issue to get the latest and best of best.

Haha. Ipad is just like big ipod touch.
Forget about customization; android is still best.
1) how many apps u use ? There is more then 350000 in google store.
2) resale value ?? Are u going to do business or for use.
3)there is no lags on note tabs.
4) if u like to use pen for writing or drawing it has sPen.
5) idk what is airplay and what it does but there are lots of feature which are better then ipad. Like allshare , opening and editing office files, adobe photoshop (comes inbuilt and free) .
Best thing is go to nearest best buy and play with both and choose best one u like.

It depends what you want to do with it.
I recently bought my dad an ipad because he did not want to use laptop, but now he does not seem to like it because he could not download songs
and videos as he used to do on laptop. And asked me if android allows that. And of course android will let you download songs and videos from net. Now he wants android just because of that.

Another annoying thing i have noticed on iPhone and iPads are ads. It's like a pc now and you can't even block it unless you are jailbroken. Beleive me i am using iPhone now that's the only thing i hate most and will switch to android just to get rid of ads. Same thing with iPad.

Thank you all for providing pros and cons with these two leading gadgets in the market. Someone told me that iOS is not suceptible to bugs/hacking/viruses, etc. Is it same with the Android as well? 

What I liked with Galaxy note is that the free hand writing in the screen readily converts to print characters. Was looking that feature in iPad or might need to buy additional accessories. Or, that may be in upcoming iPad!

About viruses,If you download all the apps from from google play store, Chances are slim or zero to get virus. Similar to iOS.

apple products are great,
1.great for techno-capped ppl(like old folks, yeh it's now being stereotyped that way)
2.great for those who wants some status symbol rather than functionality(I know Apple has been marketing it's stuffs that way)
3.great for bunch of ignorants(who for some reason always think Apple is the lord of the world with no valid reasons to back it up)

I'm not bashing it for no reason, apple had it's prime, they had unique product lines that no one had. It offered some of the things which
no one could offer. Well, that's history now. If you believe they invented touch screen, you fall under cat 3 bunch listed above.
Anyway, then came along android, needless to mention it's growing ten fold than ever. (~Google is awesome~). apple had some minor
legal scuffle with Samsung, their major parts supplier. Their business relation overtime ended abruptly after several court visits here and there they're fighting for years. apple sped up it's own demise. Samsung re-born and now we're in Galaxy era of devices. I feel sorry for
those guys who always keep longing for better version of every iteration of iphone unveiled to the public, whereas I've been witnessing their competitor Samsung is rocking world with every single product they introduced. You buy Samsung, you are good for long time, you don't have to keep longing for another round to feel better.

Anyone smart would buy Samsung product in this day and age.

Everyone around me, so far I've turned them all into android or PC people.
They're smart, they know the difference when I tell them and they pick the selection.
(Lol, my bro who was a big time fan boy, after what he saw what I was doing with my galaxy note, he gave up, he realized and confessed iphone is nothing but a big piece of crock)

I can't convince ppl over the internet, but apple stuffs are not simply worth money these days.

Bhunte, close your eyes, buy Samsung Galaxy.. You won't regret. Believe me. !!!

Unlike some people on this thread I am neither a fanboy nor a hater of any particular operation system or company. I have galaxy note1 as a phone and Ipad3 Tablet. I used both of them extensively. From my experience I have to say that Android trumps Apple phone but Ipad is better tablet than any Android tablet including Galaxte Note 10.1.  Having said that its all comes down whatever your primary requirements are? When you make a decision don't listen to fanboys.

android tablets, you get in various shapes and flavors.
Samsung galaxy tab I bought almost 2 years ago, still fills my need.
It's still fast and swift and periodically they do update, gets better everytime,
I see no need to upgrade. My tab runs all 3D intensive games like Batman,
wild blood, gangstar rio at an amazing quality, doesn't get heated up, and
stays up 10 days max with no charge but some random use. I've played
non-stop 4 hours approximately on it with full bright settings, and the battery
was used up 45%. So, 8-9 hours continuous use I think is unquestionable, which is rock-solid.
Thats what apple claims they get on their system. Right? so, not a big deal. I played around at electronic
stores to get myselt into ipad after lot of hype, but that thing simply hasn't been able to
light up my interest yet. That old blocky interface, super boring look.. am just
tired of it. I found no difference in swiftness and speed, dunno how gaming is on ipad
but so far 3D gaming on my samsung tab has been awesome. If apple tab offers same,
well.. it's same, nothing interesting.

There are some cheap version of android tab which don't live up to the expectation, now
don't compare it to high end tabs. Lol, its funny how they think all android tablets are same.
You own it, you compare and then you comment.

I ordered ipad 2 on amazon, played around with 3-4 days, returned it and got refunded.
ipad is not for me. period.

PS: If some folks are new at tablet, I highly recommend buying ipad for it's ease of use
and simplicity. Once you get used to it, and see what other folks at the other end doing,
you would want to sell it fast, we learn from mistakes, therefore I highly encourage you
to make mistakes :) 

 Bittertruth you are my man . haha

 Dont fight Just Switch
