Happy iPad day. I picked up my iPad at Pentagon City this morning. We made it a family outing and my six year old son was at least as excited as I was. We got in and out of the Reserved line a in about 20 minutes, so really a pretty good experience.

I like the iPad so far. Nice screen. Nice keyboard. Nice heft. Very few things to complain about.

Here are my complaints. My home button is a bit loud. A little too loud if you are typing in bed and don’t want to wake your partner. It would be too loud for a meeting, too. I seem to recall, though, that my last iphone had a loud home button, but that it quieted down with use, so take this complaint with a grain of salt.

I also resent that I can’t seem to use my old iPhone cable to charge my iPad. It’s like a big loyalty tax. What is is up with that? Correction: The problem wasn’t with the cable, it was with what it was plugged into. If I plug into my older MacBook pro, then it won’t charge, but it will charge if I lug it into the wall. What is up with that. More correction: charges sometimes on the MacBook a maybe when the iPad is turned off?

All in all, a great product, though. I’ve had a lot of fun with it so far.

I launched an upgrade to Nightlight for the iPad – check it out. Although I was stoked to have that out on opening day, I’m really bummed that I’m still having issues with getting my Powernap upgrade out the door. It’s seems to work fine for me, but apparently crashes on Apple’s test rig – arghhh. [Update: Powernap: Forty winks anywhere is doing just fine.]

I also launched a simple, but useful upgrade to Elegant Quadratic and launch a Pythagorean equation solver and generic math expression solver called Lil Math. These three are using a new technology that I’m developing to streamline app development – especially cross platform stuff. More about that later.
