You are fostering other points of why this is a silly argument.
It is far from "silly" to desire risk mitigation steps to verify your equipment is working while still in the field.
Its also far from "silly" to desire that one's field equipment isn't unnecessarily big, bulky, etc.
For some, it not about saving money. Its about saving weight in your carry-on bag, etc.
You are using the laptop for portability in the field but any real processing is done on your "desktop".
Of course, since some jobs and workflows are not unusual for the post-processing to literally take a couple of man-weeks. Do you really want to thus be limited by even a mere 17" screen?
BTW, does the G4 have a express slot and if so do you use it?
The 12" PowerBook never did, but it did have Firewire, which the 13" MBP just finally got. Since my dSLRs all use CF cards, the SD slot is utterly useless to me...and also too for my next planned dSLR purchase.
On another note. Pro features is not synonymous with "express card slot". Is that the only thing that made the previous 15" macbook pro a Pro computer?
The EC was part of what differentiated the MBP product line, with the obvious exception of the lobotomized-seven-ways-to-Sunday 13" version. Personally, I suspect that Apple wanted to ditch the WhiteBook, but consumers rankled by both the price and lack of FW on the 13" unibody prompted them to keep it around rather than EOL it.
Right, but there you go... sounds like MBP 13" or even MBA could handle your on-the-road job.
The MBP 13", since MBA lacks firewire, so with it, I'd have to suffer from USB-speed card transfers. I've not tried to figure out how many days(?) it would take for a 16GB CF card to download across USB.
You don't need a desktop replacement on the road. And for those who do, the MBP 17" is the obvious choice.
Exactly my point; thanks.
FWIW, when I really have to travel light & remote, even the 12" PB gets left behind as too much weight: a Hyperdrive HD80 digital wallet is 0.5kg (~1lb), so a pair of them is 1/2 the weight of the 12"...and that includes enough onboard power to backup over 60GB of data,
while also adding data redundancy.
BTW, I finally got around to dropping off the iMac for repairs.

...
I handed it over to an Apple Premium Reseller on May 20th. Mailed them last Wednesday, after 2 weeks, and wondered politely what the hell is going on... they said they were expecting parts "any day now, probably Friday". That was one week ago, still nothing. 10 more days and it's a full month!
Egads, that's lame.
I'd recommend forwarding their email to the Mothership and ask for an "Executive Review" of their service standards and if this is actually considered acceptable...and if not, what are they going to do about it.
