There were also some hardware issues, which resulted in community discontent.〔(【引用サイトリンク】title=AI official forum: Hardware " Touch Book )〕 After much speculation on the community forum, a revised v.2 Touch Book and new ''Smart Book'' product were announced.〔(【引用サイトリンク】title=AI news - Tue September 14, 2010: Announcing the Smart Book )〕 The ''Smart Book'' is based on the BeagleBoard-xM design. == Overview == The Touch Book is a netbook and a touch tablet device. It features a detachable keyboard, a removable back cover to access the electronics of the device, and several Linux distributions shipped by default and offered via a multiboot system. The default operating system launched is a custom Linux OS based on Ångström, being custom themed to fit the small form factor. Since 2010, the Touch Book comes with a multi-boot graphical interface, allowing users to run also Ubuntu and Android. Users can install other OSes like Gentoo and RISC OS.〔(【引用サイトリンク】title=RISC OS on Touchbook first steps )〕 Touch Book's major intended uses are media viewing and web browsing, although more power-hungry applications such as OpenOffice.org are available on the device. The Touch Book ships standard graphics libraries such as OpenGL ES and SDL. The Always Innovating team claims the device follows an open hardware philosophy, so that anyone can access the hardware design from the company's website,〔(【引用サイトリンク】title=Always Innovating Open Hardware )〕 modify it and redistribute it. Although the business model of open hardware is still maturing, it seems to be profitable to the company〔(【引用サイトリンク】title=Open Hardware takes baby steps toward the gadget mainstream )〕 In addition to this open hardware approach, the Touch Book fully relies on open source software. A Git repository of the entire OS is currently available, allowing for download of the latest kernel source as well as the different root file systems.〔(【引用サイトリンク】url=http://git.alwaysinnovating.com )〕 A community of contributors has emerged〔(【引用サイトリンク】title=Touch Book contributors )〕 and is interacting with the Always Innovating developers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Touch Book」の詳細全文を読む スポンサード リンク
