Ipad question?

I recommend using Drop box. Just upload the PDF on your computer then download the drop box app to your iPad. After that you just open it with your iPad and you're done

 

You can't use external storage on the iPad like that. They work (sort of) with photos and videos, but you can't view directly from the card, they have to be imported into the Photos app. And, AFAIK, you can't access an external card through any of the file viewing apps like Goodreader or iBooks.

Easiest way is wirelessly with Dropbox or Goodreader followed by going through iTunes directly.

 

You can also send the files by email and open them in the iPad.

 

There's a Windows program called iphone browser that allows you to copy files straight to the PDF reader's documents directory.
Also an app like Quick Office opens a web interface for exchange of files.

I don't think the native camera app has a timer, but there are plenty of third party camera timer apps,
time lapse camera apps exist as well.

 

The only way to get in effect an SD reader for an iOs device is through the Airstash device that is an SD card reader that creates a Wifi network(no internet) Then you can use their Airstash app or a few other apps to stream from the SD card.

 

This is what I usually do. I send an EPUB or a PDF and open it from the email. It then goes right to the library. Pretty simple.

 

The N7 is actually a really good tablet, Jelly Bean works quite well and the 7" form factor works well for certain apps. However, for me, it still suffers from one major flaw...it's not in the iOS ecosystem that I am too heavily invested in.

What else is missing from the N7:
No 3G
No external storage cards and limited internal memory
No significant 3rd party support (cases and such)

 

I've also heard good things about the Nexus 7. As seajay, I'm far too invested in iOS to switch. I have an Android phone that I'll be switching back to an iPhone this month. I ended up having to switch back to Verizon and they didn't have the iPhone when that happened. I miss having the iPhone and will look forward to using all the universal apps that I've been using on the iPad until now.
