Kupitero is a technical buff and had been fiddling with personal computers since 1978. He started with the Motorola-powered Commodore PET until he upgraded to the then, state-of-the-art, and legendary Apple II in 1980. From then on, he had been an avid fan & close watcher of the development and growth of the personal computer industry.

A self-confessed Steve Jobs fan, he has attended many MacWorld Expos and had seen oodles of COMDEX (Las Vegas) shows as well.

1. Use a multi-function router if you have a broadband connection to max out the usage - and your money!

2. Unless money is no object, upgrade your PC on the second processor revision - not  immediately on the next.  Hence, if have a P4, upgrade when the Quad-core is released.  If you have a Mac - upgrade to the G5 or the Intel Core 2 Duos if you have the older G3.

3. Increase your computer's memory and use the latest BIOS and tweak it -- to max out the speed.  Even an  old Pentium 233MMX  with 128MB of RAM can outperform a 333 Mhz Celeron running with a paltry 64MB of RAM.

4. If you're using dial-up, NEVER  buy a WinModem (or CPU- assisted modem).  Also, avoid motherboards with built-in video and modem.  Built-in sound should be okay.

5. It's better to buy an old but durable laser printer than a fancy, new  ink-jet printer -- lasers will cost you less in the long run!

6. WiFi may be in, but,  crossover cables can still do the job if you only have two PCs to network - and, it is much faster !

7. Plan, before you 'burn' any CD or DVD...and, help save the environment!!

8. Use a KVM (Keyboard-Video-Display) switch...if you have multi-platform PCs in the house to minimize clutter.

8. It's a good idea to refill a used ink-jet cartridge BUT only up to a certain number of times - 3X or 4X would be ideal.  Then, buy a fresh one - the hassle is not worth your precious time!
