my predictions in the next 5 years:
Notebook will throw out desktops for the public. At the end, desktops are for the business people and big towers for the gaming bunch that constantly upgrades.
Netbook will evolve to be lighter and faster, more like Macbook Air type of devices. So families will have a bigger 15 inch plus Notebook as desktop replacement. one or two netbooks for kids to avoid competing for the big desktop replacement notebook.
PDAs and even GPS will be history!
Phones will remain phones, throw in GPS plus the simplified digital video camera and digital still camera. It doubles as mobile computer for the net and server for other mobile devices on the go.
E-readers incorporate PDA functions, will be the fourth net enable devices, to go online, just to serve the net, but still primary to read a book with out stressing the eye before bed for the matured... Kids will use them at school for lighter school bags!
Ereaders will be able to sync with mobile phones (mobile server), use wireless technology, integrate at class rooms.
However, I still don't hear any breakthrough on battery front! Just as super conduct material, the all promising long lasting powerful battery is still out there in the labs!
IN fact we already has the ability to produce a great phone that does everything, trouble is they must constantly hook to the sockets in the wall.
