With the point-and-click way of surfing the Net, is it better to wait until one operation finishes (and the Netscape stop button turns from red to grey, for example) before clicking on another link? Will that, as seems likely, slow down the whole process of surfing? Or, if your answer is no, how will the Internet network work in response? Will it abort the process initialised in the last operation (which may have been done only seconds ago) and immediately start accessing the new link? BENJAMIN TANG Hong Kong This is more a case of 'how will a particular browser respond' rather than one of how the Internet, or the Web in this case, will react. The Web would not give a hoot. The two most common browsers, Netscape and Explorer, both abort a working download and move on to the next link if you click on it. If you go back to the previous page, it will get what it has already downloaded from the computer's cache memory and resume downloading what it has not received. For example, if you go to the South China Morning Post Web site at www. scmp.com and click on the Classified Post link before all the graphics on the homepage have been downloaded, your browser will simply begin downloading data from the Classified Post page. Go back to www.scmp.com and it will pick up where it left off. This does speed up the surfing process, and since the browsers themselves have been designed to work this way, there is no need whatsoever for you to sit twiddling your thumbs until one page loads in its entirety before moving to the next. Weeks ago you recommended the Psion Series 5 palmtop. Have you considered the Philips VELO with eight-megabyte memory, built-in modem, et cetera? Any comments on this model? SOPHIA LEE Happy Valley At the time I had not had a chance to play with the VELO. I have since. Unlike the Psion, the VELO runs on the Windows CE operating system (the Psion has its own proprietary system). As far as Windows CE palmtops go, the VELO is right up there with the best in terms of design and features. The built-in modem (it pops out somewhat like the X-Jack in Megahertz [now 3Com] modems) definitely is a plus. But this is somewhat negated since the VELO does not have a PC Card slot. Philips' logic appears to be that if you already have a built-in modem, you would not need a PC Card slot. What about for a wireless modem, though, one that connects to a mobile phone? After all, one of the nice things about these handheld devices is that you are supposed to be able to use them on the go. The VELO is also fast, compared with other CE devices. That is a combination of its high memory (8 MB is a lot to come standard in palmtops these days) and the rest of the VELO's internal design. Tested against the HP320LX and Casio's Casiopeia, the VELO is easier to type on, but my big fingers still had plenty of trouble. This is one area in which the Psion is unbeatable. Nevertheless, among Windows CE palmtops, the VELO is definitely on my 'OK to buy' list.
