I'm not going to hold my breath on the actual RAM number until we see an iFixit teardown. Due to just the shear size, the iPad mini has always had half the ram as the regular sized iPad. I wouldn't be surprised if the Air had 2GB and the Mini had 1 GB.
Understandable, some people do, some people don't.
I'm one of those people who do. For $10, if this thing included IRC, I would switch over in a heart beat. If it also included SKYPE? Oh man, the things I would do to the developer who made it...that would be heaven.
Less apps open usually means less memory consumption, and overall less clutter on my desktop.
They are fantastic pens, too. I've had one since high school (so...about 8 years now) and I've refilled the ink cartridge all of three times. A very VERY solid investment for writers.
