Funny - the 8 yo. laptop I keep around is still in use (almost daily). It's an IBM Thinkpad a21m (one of the early 'desktop replacement' models, if you will). Over time, I:
- added/replaced SDRAM
- replaced the Win2000 OS with Ubuntu Linux 8.04 LTS
- replaced the 2.5"x12mm 20 Gb HDD.
Cost:
- $40 for a new (2007), larger (80 Gb), MUCH faster (2 platters, 4800 rpm, 2 Mb of cache) HDD. Replacement: easy (a2x Thinkpads use a drawer design for HDD bays, physically replacing the disk can be done in less than 5 minutes)
- 30 minutes to install said Linux OS (updates happen seamlessly)
- $100 (over time) to replace the original 128 Mb with 512 Mb of RAM.
- $30 for a Wi-fi PCMCIA card.
And since a P3-750 can kick a Celeron 900 around (L2 cache), this makes the machine pretty much as powerful as an early netbook - with a larger screen and a much more comfortable keyboard.
The original battery still works.
Now, this is an extreme case: apart from IBM, I don't know of any manufacturer that made machines that didn't spontaneously start decaying after 1-3 years. And it's not without its faults: the integrated Ati Rage Mobility M1 chip can barely run Google Earth in Linux (well, it simply refused to run it in Windows, so...) and USB 1.1 is not fast enough for external HDDs.
But a cost (everything included, I sometimes use a PCMCIA USB 2.0 card on it, but not exclusively) of $300 for a laptop that initially cost me $2500 and lasted 8 years, well, I consider it a good deal.
For a sh*tty 2005 HP, Acer or Toshiba though, the article is spot on.
