I' ve been used various kind of "Small digital gadget" for long time such as Sony's Premini phone or Vaio U, IBM's PC110 palm-top pc, Toshiba's Libretto, Palm device etc. The history was started from ancient "Galapagos keitai(cell phone)". This is one of my hobby and kind of life work.
You can see these cute and unique small gadgets I've ever used with my personal review comment on this site.
By the way, somehow I prefer larger size vehicle instead.😃
