We can’t quite see why IBM Corp is canning its butterfly notebook keyboard design that everyone oohed and aahed over last year, particularly because it was such a moneymaker. The ThinkPad 710C was launched in the spring of 1995 and held an 11.5-inch keyboard and 10.4-inch screen in a 9.6-inch machine, from which a sliding keyboard would emerge in two parts and flow together like, gasp, butterfly wings. IBM said last year that it received more orders for the 710C than for any other product in the history of the IBM Personal Computer Co and that ThinkPad business generated about $2bn for the company (CI No 2,640). IBM says users want wider screens now – its latest ThinkPad has a 12.1-inch screen – and so the butterfly is, officially, extinct.
