G5 on my main working system - multiple monitors but we use an iBook on the office desk now and my daughter swithced from a tower to an iBook with a mouse.
We will be campaigning this holiday season on dual use systems ( aided by a pile of 12" beauties ).
With many graphics clients moving to better boxes and OSX boxes the portables offer a lot and a good transition.
The only downside is lack of flexibility down the road if something simple goes wonky
But at current prices there is a "throwaway" aspect that is kind of worrying.
I think for many a tower + a portable is a great strategy and they are certainly no slouches unless you are into really heavy duty use.
My daughter was skeptical after having an 867 tower but the 900 iBook was "jest fine, thankee"
I am using my new 14" iBook for iMovie and iPhoto, and for venturing into the land of ehMacLand (thanks to the Zoom feature), and my Dell 8300 desktop for teaching my web courses (Safari still has issues with WebCT), and for grading printed assignments (since I have to spread out and I don't want a staple to get near my iBook). It is a good balance.
Traded a G3 B/W for a foray into iBook land. I am getting used to the keyboard, albeit slowly.
I have a 17" external monitor but I find the 14" screen has enough real estate to function.
It's really a lot of fun, the iBook is pretty powerful.
I could not imagine not being able to pick my machine up and take it wherever I want.
Powerbooks (12" PB G4 and PB 140) and PC Laptops (Thinkpad T23, Toshiba Tecra 5200 and NEC Versa LX), it is for me... well not counting the kids PM 5xxx's, and my colectable Colour Classic, or the 3 Classic's, the Classic II and the 512
My new 12" G4 iBook is a pretty exciting machine that I can't seem to leave alone, however I'm still addicted to the speed and real estate that my desktop offers.The iBook was purchased to cover my work needs while the desktop is for all of my dream projects. Having both makes life pretty comfy.
G4 Desktop with 21" monitor is primary. Also cube and 21 Studio display in my son's room, however he and my daughter fight for the 14" ibook though it mostly stays put in her room. It's mine when I must do work outside of the home using a mluetooth phone for connection. At home all are wired via airport card in my G4.
As a commercial artist, my G4 867 and 21"Cinema Display are my work machine. I love the real estate on the monitor, and I don't get the eye strain that I did with CRT monitors. Just became a laptop owner in the last month and love the portability, it's become my communications machine- email, internet and it's an additional back up. I'm thinking about a small drawing tablet for the iBook, for on the go sketching and painting.
