wrote: On laptops, USB is very, very great. Maybe USB is one of the greatest ideas of the laptop computing. Without USB, you have nearly no ways of attaching hardware to laptop. The PC-Card (PCMCIA) and Cardbus interfaces were intended to be for this, in exactly the same way that the ISA and PCI busses are the mechanisms for attaching harware to a desktop. Without USB, you will need: - PS/2 hole for keyboard - serial port for serial-attached hardware or serial mouse - PS/2 hole for mouse - parallel port for printer - custom PCMCIA card for scanner and so on. With USB, all you need is a hub, and only if you have more then 2 devices to attach to the laptop. Max Port replicators have done this type of thing very well long before USB. They are also more robust devices designed especially for easily plugging/unplugging daily for years. |

With USB I need:
USB hole for mouse. Serial port for printer and other serial devices. No. USB hole for printer :-) Cardbus slot for Ethernet/Modem or SCSI or firewire. Firewire and Ethernet are inside the laptop (the modern ones), the modem is either inside or USB one, SCSI - yes, SCSI requires the CardBus slot. USB port for handheld. Nominally 12 MB/s, practically 56K. Dunno on handhelds, but with USB-to-USB bridge (used to connect laptops together) or the scanner the speed is much higher. 12MB is the physical layer speed, packet headers and transaction phases require some overhead. Another USB hub because the first one keeps resetting the mouse when I plug in the annoying USB flash memory dongle. Bad hub, which violates the spec. And if I need to read DVDs or get online: New laptop with cardbus slot for ethernet/SCSI/firewire because USB is still too frigging slow. Large laptops have the DVD drive in them. External drive is necessary for smaller ones only (subnotebooks, 1.1kg weight). Modem is also there. For faster connection, you can attach the cellphone to USB outlet (or use Bluetooth attached to USB outlet) and use GPRS, or use the USB-attached ADSL modem. -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation http://www.storagecraft.com |

USB. They are also more robust devices designed especially for easily I disbelieve that on-the-knee-made port replicator (which violates lots of specs - PS/2 one for sure) can be _more robust_ then USB. -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation http://www.storagecraft.com |

Far be it for me to sing praises of Win95, but it does 99% of
everything I need or want, and I can live with 32G slices, and I have no network problems. My Win95 systems, given sufficient memory, Am I right that Win95 cannot utilize more then 64MB of host memory? -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation http://www.storagecraft.com |

Cardbus slot for Ethernet/Modem or SCSI or firewire. Firewire and Ethernet are inside the laptop (the modern ones), Ah, now you're changing the rules. Adding more ports. USB port for handheld. Nominally 12 MB/s, practically 56K. Dunno on handhelds, I do. Another USB hub because the first one keeps resetting the mouse when I plug in the annoying USB flash memory dongle. Bad hub, which violates the spec. Then it seems at least 3 out of 4 "compact" hubs violate the spec. New laptop with cardbus slot for ethernet/SCSI/firewire because USB is still too frigging slow. Large laptops have the DVD drive in them. Ah, so that's another non-USB port. External drive is necessary for smaller ones only (subnotebooks, 1.1kg weight). Modem is also there. And another one. So... with a non-USB laptop I have: PS/2 port for mouse. Serial port for handheld or printer or router config. Parallel port I don't use. Cardbus slots. Ethernet. Modem. Media bay. PS/2 splitter if I want an external keyboard. Now, with USB that's been reduced to: USB port for mouse. USB port for handheld or printer. Firewire port I don't use. Cardbus slots. Ethernet. Modem. Media bay. USB hub if I want an external keyboard. USB serial dongle for router config. This has clearly reduced clutter. Actually, what I have on my laptop is: USB port for handheld. USB port for keyboard. PS/2 port for mouse. Ethernet. Modem. Media bay. IR port. Serial port. Parallel port I don't use. Don't get me wrong. USB is useful. But... removing the PS/2 and serial ports is a step backwards. -- I've seen things you people can't imagine. Chimneysweeps on fire over the roofs of London.

And if I need to read DVDs or get online: DVD-ROM built in. New laptop with cardbus slot for ethernet/SCSI/firewire because USB is still too frigging slow. In reality, the only cardbus card that I use is an old 802.11b card that I use for wireless networking. My printers all connect via USB. I must admit that I do miss the serial port on my HP laptop, I work with a lot of equipment that wants to be set up via a serial port. -- Eric Lee Green Linux/Unix Software Engineer seeks employment see http://badtux.org for resume -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

I think I was unclear. I just mean that the connector's tend to be beefier. It usually isn't possible for a user to jiggle it when inserting or removing. These connectors *should* last longer. There is also no possibility of trying to insert it the wrong way (like a USB port on the rear of a laptop) which is a little easier if you are rushed. Of course there are design compromises and many caveats when making generalizations about proprietary solutions. Whether or not you find them unsatisfactory, they have offered similar functionality as discussed before USB was available. |
