Well, it's sad to say but I'll soon be retiring my Ti83+, as it can no longer keep up with what i need to do. Don't get me wrong, it's a great calculator, and was a nice asset on many a math test, but it doesn't cut the mustard with simultaneous equations with imaginary numbers.
So, to cut to the point, i just bought a HP 50G from walmart, and am awaiting it to come in sometime next week. Most people i know have a Ti89 Titanium, but i prefer a more open calculator, and a few good friends, the main one being Kevin, recommended it highly, so i went for it.
It looks better specs wise than an 89, since it uses an ARM processor, has 512K ram, 2 meg flash, an SD card slot, and also touts irda, usb, and serial connectivity. It also has a RPN stack, which i am looking forward to greatly. It's also fairly open, with a c compiler and other niceties not found with most calculators.
Check back sometime next week for the updates and maybe a set of "unboxing" pics.
