Need advice on laptop purchase. Need laptop for presentations and mostly for travel. Will be loaded with MS Office Pro and Adobe Creative Suite Premium. Most of the graphics work will be print production. Looking at Ibook with following specs: *1.256GB DDR266 (256MB built-in & 1GB SO-DIMM) 60GB Ultra ATA drive SuperDrive (DVD-R/CD-RW) AirPort Extreme Card Bluetooth Module Keyboard/Mac OS X - U.S. English 14.1-inch TFT XGA display 1.2GHz PowerPC G4 ATI Mobility Radeon 9200 w/ 32MB DDR video memory Anyone using the above config? if so, how well does it perform? Considering the Ibook since it's over $600 cheaper than powerbook. All comments appreciated. Thanks!
