Go up one level in this thread
I believe you underestimate resources that people want to have, as well as progress rate. For example, look at the iPaq (http://www.compaq.com/products/handhelds/pocketpc/pocketpc_bridge.shtml). Right now flagship model has 64Mb of RAM. That is only 2 times less than you predict 5 years from now. It have no hard drive yet, but look at the IBM microdrive. It is *almost* small enough to be constantly attached to the handheld. CPU is only 200MHz, but this year next version of Intel's ARM CPU (previously called StrongArm II, now renamed XScale) will go into production with peak clock rate of ~700MHz and very reasonable energy consumption. And I bet it'll find its way into next iPaq version. And of course, that handheld runs MS software :-) :-) :-) Eugene On March 22, 2001 at 11:05:20, Christophe Theron wrote: >On March 22, 2001 at 09:42:24, Robert Hyatt wrote: > >>On March 21, 2001 at 22:14:25, Christophe Theron wrote: >> >>>On March 21, 2001 at 21:32:09, Robert Hyatt wrote: >>> >>>>On March 21, 2001 at 19:03:55, Christophe Theron wrote: >>>> >>>>>On March 21, 2001 at 18:14:46, Robert Hyatt wrote: >>>>> >>>>>>On March 21, 2001 at 17:30:44, Andrew Dados wrote: >>>>>> >>>>>>>On March 21, 2001 at 17:00:29, Robert Hyatt wrote: >>>>>>> >>>>>>>>On March 21, 2001 at 16:21:59, Peter Berger wrote: >>>>>>>> >>>>>>>>>On March 21, 2001 at 15:58:38, Slater Wold wrote: >>>>>>>>>>Now.
