My HP Prime G2 review.

RE: My HP Prime G2 review.
Hello,

The text is blurry on Prime, NOT because of pixel density, but because the fonts are rendered using dithering (same as on your computer), while the fonts on the TI are not dithered (like they used to be on windows XP and similar).
If you look on the HP, you will see that "pixels" on the edge of the characters have gray scale while on the TI (if I am not mistaken) it's white or black with no in between...

Cyrille

Although I work for the HP calculator group, the views and opinions I post here are my own. I do not speak for HP.

RE: My HP Prime G2 review.
My Nspire CX CAS running OS 3.1.0.392 (it's still running that old version, instead of OS 4.5.x, due to the annoying anti-downgrade protection, even though that can be worked around in various ways) does not use font antialiasing, but my CX II-T CAS running OS 5.0.0.1509 does. Use of antialiasing would need to be checked on newer CX I OS versions.

RE: My HP Prime G2 review.
OK so it appears I need to make a correction to my review, thanks Cyrille for clearing that up! One question though, why does the Prime use dithering/anti-aliasing for the fonts if it makes it so blurry? Also, wouldn't the dithering look much less blurry on higher resolution displays?

I agree thenozone, larger pixels are easier to see and the Prime is by no means unusable at this resolution. Now that I understand that it's not the LCD itself making some things blurry perhaps it will change my opinion. (I can still dream of a 720p micro-LED calculator screen though Tongue)

debrouxl that's an interesting fact. Which calculator in your opinion is easier to read? Are there other calculators out there that use this anti-aliasing to compare to?

Thanks for your responses guys! I have a unrelated question: I've swapped out my Prime's original battery for my Galaxy S3's slightly better 2,300mAh battery and now when I turn the calculator on, it always 'gains charge' after a few minutes (the battery indicator always goes from say 50% battery up to 75% or from 25% to 50%). Why would this be?

It's been years since a significant part of my usage of calculators has become testing libti*/gfm/tilp, and I mostly use calculators which do not anti-alias fonts, so I'm not very qualified to compare Smile

RE: My HP Prime G2 review.
Hey it's been a while. Due to new information that came to my attention (e.g. the font dithering and the G2 being released in the US) and because I wasn't happy with the negative tone that my review seemed to have, I've revised a large part of it. Most of the facts remain the same, however I've rearranged some of those facts and I've added more information along with letter grades for each topic I cover. (A+ being the best and F being unacceptable) I've edited the first post to include these changes. A list of all the scores is at the bottom of the first post. Please let me know if you like the change!

Bleh, in hindsight it wasn't such a good idea to jump into making a video so soon, now I've got to re-record and reshoot footage! Tongue

RE: My HP Prime G2 review.
That was a meticulous and outstanding review. Always we want more, we want perfection, but engineering is always a set of compromises. What your review shows is that overall the HP Prime does what it needs to do in the important ways. I've done photography since age 16 and I was a shooter later in life and the arguments never cease over this versus that. I sold photographic products in the early part of life and the amateurs would argue Nikon vs. Minolta and all that. The pros would come in with a dented camera around their neck and they'd say "It's a tool, that's all, if it gives me what I want that's all I care about." The pros take what tool is at hand and get it done. However, reviews are important starting points before you decide on an expensive tool and your review will be a big help to people considering the Prime vs. the competition. I enjoyed reading it!

Thanks harryp! I suppose you're right, there's always people for and against certain companies, but if the tool gets the job done then at the end of the day it doesn't really matter which side you choose.

You may not be aware of this but the Connection Kit does actually sync the Prime's clock to that of the computer whenever you connect a Prime to it.

There are only 10 types of people in this world. Those who understand binary and those who don't.

I was not aware of that! That's really cool, I'll have to add it in!
