Aargh! The colours!
AT less than 0.5MB, this little thing is quite powerful for its weight. Unfortunately, the hideous colour scheme is difficult to ignore. The tiny key digits are difficult to read, particularly on the dark blue keys. - And just when you think you may be able to persevere, the operator keys also get wiped out by suddenly changing to that crazy blue for no apparent reason (a very odd, and most unwelcome peculiarity!). Please subdue the colour! In its present form, it's virtually unusable, which is a great shame…
