Daystar Ships CPU Upgrades for ALL PowerBook G4 Titaniums!

Users get speed gains up to twice as fast as their current systems.

Buford, Georgia, July 27, 2006 - Daystar Technology, the original Mac
Performance Shop, delivered another milestone in PowerBook speed today. The
introduction of the new XLR8 CPU upgrade for the Titanium PowerBook G4
series.

This new CPU upgrade delivers up to 100% faster performance for owners of
most classic Titanium systems. The PowerBook G4 upgrade dubbed, "XLR8
MAChSpeed G4 Titanium" is a factory installed upgrade, has been shipping
for 3 months to "pre-release" customers and is available immediately.

No Experience Required.

Like the XLR8 MAChSpeed G4 Pismo, Lombard, Aluminum and iMac Flat Panel CPU
upgrades, the PowerBook G4 upgrade is a factory installed CPU upgrade.
Users simply place their PowerBook in the provided box. The shipping,
testing, installation and 100% quality assurance is handled completely by
Daystar's Apple Certified Technicians.

No Compromise, Just Raw Speed.

The CPU is the primary bottleneck on a PowerBook G4. To maximize speed and
compatibility, Daystar uses the latest model, highest rated Freescale
PowerPC CPUs. It runs transparent to the operating system and is fully
compatible with future OS's. The result is a system with much faster
processing power, and improved performance in the Finder and every
application.

QuickTime encoding is up to 75% faster

Photoshop performance rivals the MacBook Pro!

48 hour, factory installation via Apple Certified Technicians.

Compatible with Classic and Mac OS 10.3.5 - 10.4.x... and beyond.

Includes XLR8 MAChSpeed Control for 100% compatibility

All upgrades warranted with Daystar's exclusive 90/720 warranty program.

"We have already upgraded a number of users via our Pre-release program -
it is rock solid", said Gary Dailey, president of Daystar. "This new
upgrade allows users to get high performance without sacrificing their
classic compatible Titanium system, or settling for someone else's logic
board."

Performance for Most PowerBooks.

The new XLR8 MAChSpeed G4 Aluminum CPU upgrade is available for all
PowerBook G4 Titanium systems.

The base price of $449 includes all parts and labor and US Ground Shipping.
