I thought a touch screen interface would be a wonderful thing for a calculator, and the descriptions leading up to the ClassPad's release were tantalizing and exciting. To sum up, what I feel I actually have is a strange mixture of poor planning and deep insensitivity to users' needs. <br /> <br />The display contrast is terrible. And if you try to remedy this with a strong light source, you trade horrible contrast for double images caused by shadows. The 'screen protector' Casio provides is no help, either. It adds a reflection problem to the mix. <br /> <br />The huge amount of screen real estate seems like it would be a wonderful thing. Unfortunately, it is used by the calculator's OS with stunning inefficientcy. Even performing basic calculations can be frustrating. As soon as you bring up the soft keyboard, a full half of your screen is lost. Answers or problems that exceed one line are simply truncated, followed by an ellipsis and a tiny, tiny triangle you must tap to see the rest of the line. There is no way to display the whole line at the same time. <br /> <br />The touch screen interface, the most intriguing aspect of this calculator for me (before purchase), is very poorly implimented. The calculator has a very basic keypad for entering numbers and basic functions. It also has dedicated keys for three variables, x, y and z. Oddly, they have no keys for storing anything in these variables. The only way to do it is using the 'soft keyboard', a touch screen keyboard with several panels of keys, all of which are quite tiny and very difficult to see due to the poor display. Imagine being in an engineering or technical environment and having to pull out a stylus every time you wish to do anything but the basic four functions. You cannot lay this calculator on a table and use it with one hand effectively, unless you wish to try to balance the stylus in your remain 2 801 days ago Classpad 300 PLUS The Bad <br /> <br />first of all i have no complaints about the screens contrast but but my gripe is that the screen seems low on qaulity, why has the fx series at �60 got colour when this doesnt - this would help to make the overcrowded screen become more approachable. <br /> <br />While using a stylus may be fun, the novlety wears of and you find yourself doing basic calculations in your head as doing it on the calculator takes longer. In fact most of the functions with vague icons you learn about in the instructions not by intuition. <br /> <br />i dont think its worth �150, the only thing i can see being worth a lot is the operating system, everything else, the screen, bulid quality, stylus, software, plastic cover are below par. i know a palmtop with good software while losing a few features is the same price but better quality <br /> <br />The Good <br /> <br />Once you learn to use its interface, you have an extremely flexible machine. powerful and useful for most mathmaticians or engineers. i have found even very advanced expressions are catered for in the softkeyboard. 3d graphing is still simple to use and is one application where the classpad shows its uniqueness, while complex functions are graphed much quicker than lesser models. i see it as a small extension to my pc, allowing me to check processes that may take longer to implicate in more detail on the computer itself. microsoft derived toolbars are easier to use and provide convienient functions such as cut/paste,save,select all etc, therefore although you get confused occasionaly you are rarely lost in its interface. <br /> <br />conclusion <br /> <br />As a student i find this calculator useful and i know it will have greater use once i graduate, but its probably too much for an average student or smalltime number cruncher. Either for somebody who is on a very steep maths learning curve or a professional- ie not me. 3 801 days ago New "Classpad 300 PLUS" has enhanced screen The major drawback of the Casio classpad 300 was its screen. The constrast was so poor that it was hardly usable at all. <br /> <br />Now Casio have replaced the Casio Classpad 300 by the Casio Classpad 300 PLUS, with a dramatically enhanced screen. The constrast is now very good under most lighting conditions. The operating system has also been enhanced, offering amongst other things a choice between the standard characters set and a bold characters set. <br /> <br />All in all, this makes the Casio Classpad 300 PLUS one of the most powerful, integrated and easy-to-use graphing calculator ever. 5 801 days ago THE BEST AND EASIEST CALCULATOR EVER! This calculator is amazing! It does everything the Texas Instruments ones do and even much better! It's very easy to use. Drag and drop. I think this should be the standard for the next generation calculators. The battery lasts forever! I don't see any problem with the LCD screen at all. It's CRYSTAL clear even under below average light conditions. Even my younger brother in elementary school has no problems using it at all! I bought one for myself and another for my fiance! 5 801 days ago Yes, It is true. The display is awful. I totally agree with the previous reviewer. I removed the protective cover (as suggested by another reviewer), it did not help that much. The only way I can see the screen is when I place the calculator under a desktop lamp. <br />I wasted $150. What a shame. 1 801 days ago Merchant Details for Amazon Overall Rating: 4 out of 5 Rating Provider Rating Rating System Reviews Last Updated BizRate.com 9.0 Scale 1 to 10 Read Reviews 30+ days ago ResellerRatings.com 6.24 Scale 1 to 10 Read Reviews 30+ days ago  We thought you might be interested in other BEST DEALS that we found for you: Fax Machines HEWLETT PACKARD-Q7270A in Fax Machines Hp Fax 1040 Faxes at up to 6 seconds per page 14.4 Kbps modem Incoming fax memory: 100 pages Auto... 5 Listings Best Price $78.25 Save up to 33% Calculators TEXAS INSTRUMENTS-TI83 in Calculators Texas Instruments TI83 Graphing Calculator 5 Listings Best Price $89.99 Save up to 28% Labeling Machines BROTHER-PT1600 in Labeling Machines PT1600 P-TOUCH LABEL MAKER PORTABLE TZ TAPES 6 Listings Best Price $100.57 Save up to 23% Shredders FELLOWES-34125 in Shredders Powershred 120C-2 Shredder Powershred 120c-2 shredder 6 Listings Best Price $279.87 Save up to 51% FELLOWES-38325 in Shredders Fellowes Powershred 320 Strip Cut Shredder with 18-20 Sheet Capacity 4 Listings Best Price $799.98 Save up to 22% FELLOWES-38427 in Shredders POWERSHRED 420HS-DOD APPROVED HIGH SECURITY SHREDD 5 Listings Best Price $1,881.95 Save up to 26% FELLOWES-3218701 in Shredders FELLOWES Powershred SB-87CS Small Office 15 Sheet Confetti Paper Shredder The innovative Fellowes... 6 Listings Best Price $139.60 Save up to 29% FELLOWES-38327 in Shredders POWERSHRED 320HS DOD SHREDDER 4 Listings Best Price $1,574.99 Save up to 18% All Best Deals *Pricing and product information listed is obtained from the merchants and is subject to change without notice.
