Just out of curiosity: Would you choose the Prime over the Casio for the same price? I guess so as it has touch screen a lots of memory, and it looks amazing! Do you think its programming languaje is useful for doing interesting things apart from Maths aplications? (As I said in previus posts I am a Computer Science student and my Maths are not great (yet), so I love to 'play' with calcs BTW, I am learning Casio Basic with the CG50 and I'm loving it.

For the same price, I'd choose the Prime over the CG50. I would have bought one earlier even at the higher price, but there was more uncertainty over the hardware revision you'd end up with from online retailers a year or so ago, so I thought I'd delay the purchase of a Prime and bought an NSpire CX CAS instead. I bought the CG50 when it came out because I have a soft spot for Casio calculators and didn't already own a CG10 or CG20. (My first scientific calculator was an fx-39 I think, or possibly an fx-29. My first programmable calculator was an FX-502P plus an FA-1 cassette tape adaptor.)

Feature wise, the Prime is faster than the CG50 and has a better screen, and the wonderful CAS. I do think the built-in apps on the PRIZM series (including the CG50) have been implemented well. Programming wise, the Casio BASIC looks a little clunky compared to HP PPL, but the Casio PRIZM environment isn't as locked down as the HP Prime's. Apparently, programs written in HP PPL on the Prime run pretty fast, so that's not much of an issue.

Quote:I bought the Casio from Ryman for 89.99, which is a really good price, but the offer (not only the offer but the actual listing of the calculator in their website!) comes and goes unannounced, but you just need to check the website and when the offer is on, go to a Ryman store with stock of the CG50 and... bang! they will match the price

They were a similar price on Amazon the last time I looked two or three weeks ago, which is why I was surprised they've gone up by about 25 pounds to 115 pounds, and according to Amazon, that's a price reduction from 140 pounds! Meanwhile, the newest model HP Prime has dropped a pound in price to 117 pounds.
