HP 48G+ over 50G?

[cdodds]

Hi,

I'm a land surveyor and I like the hp50. I also have a 48GX with a SMI (survey) card in it. It is really hard to beat SMI, though I've heard people say the same about TDS cards. I wish SMI would run on my hp50. I do have custom keyboard assignments set up on my HP50 so that I can add and subtract regular numbers pushing the "+" and "-" keys normally but if I long hold the keys it will add and subtract hour minute seconds. I too like the fact that when I'm in the office I can power the calculator off the usb port. I have never used a 48g+ but I'm sure if you buy a hp50 you won't regret it. I like the 48GX but the programming power of the hp50 is amazing. I hope this helps.
