3 weeks ago I upgraded my 32GB iPad2 to a 64GB iPad4. (And gave the iPad2 to my wife).
Love the improvement of the 4 over the 2. There are always quality issues with each new release, so by waiting a few months to buy the 2, I received a perfect one. Apple has worked out all of the bugs of the 3/4 so buying a 4 now is good timing...unless one will have buyer's remorse should the 5 get released in a few months.
I have found that the iPad4 + smartcase + Apple BT keyboard + inCase Origami workstation makes a terrific portable solution. I just returned from a week-long intensive bootcamp training seminar, left my MBP at home and only used this configuration. After 8 hours of typing each day, I still had 50% battery remaining on the iPad... while my classmates with notebooks had to recharge at least once and a few twice, during that time.
As for an ASQ solution, sorry but I can't be of any help in that... I haven't found one.
