Query: HP continues to be #1 for high end calculating

I was a 10-year user of a 48g. Got the 49g+ to catch up with the times, love it. Back in school of a EE degree, use it every day, very powerful. I've had it for a month and already it has outpaced the TI, which isn't a bad calculator, it just that for the professional/engineer type this HP seems so much better. In fact I've already managed to convert 2 long time TI users. Once they saw what this HP could do they realized the myth/ledged was true. Other stuff - keyboard is fine & the SD card is great, right now my calc has 512 mb of storage. Wow. As far as RPN, give it two days and you'll never change back. Great buy.
