If it's anything like the 300s or the 35s reissue, it's going to be crap. Just about anything coming out of HP since the HP48 is utter shit.<p>For ref the 300s buttons don't work properly and the OS is simply 100% stolen from Casio FX-series which are 1/3 the price. The 35s is buggy as anything and can't even display a single FP value accurately without having to scroll. The HP49G is better but still to expensive.<p>Save some cash: buy a TI89 or a second hand TI-92+ if you can be bothered to carry it around.
