Laptops

I was just looking at my laptop (Dell Latitude D620) and wondered about a few things …

  • Why do they bother putting RS-232 ports on laptops anymore?   I haven’t seen a device that connects via RS-232 in years.   The only devices I can actually think of that used a RS-232 port was an external modem … and most laptops have modems built in (not that they’re used much anyways).
  • Ditto with a parallel printer port.   Most printers that I’ve seen in the last few years have been connected by USB (‘course my laptop doesn’t have a parallel port, but Ginny’s does).
  • Why bother with a DB15 video connector?   Wouldn’t it be better to just go with DVI?   If you need a DB15 video connector, you can use an adapter.
  • The hard drive on my laptop uses SATA … I really wish there was an eSATA connector.   I tried putting an eSATA card in the PCI slot of the D/DOCK port replicator, but the BIOS wouldn’t recognize it (which is fairly logical, considering there’s no guarantee that the card would be there all the time).

On a somewhat different, although related, topic … I really wish someone would make an inexpensive tablet computer.   I have an idea for a nice little appliance application that would be perfectly suited to a tablet computer.   All it would need is a 12″ display, 512mb of ram, 4gb to 8gb of flash disk, wifi, and Linux.
