Option one is by far your best option, and a total solution.
The iPhone capability that is most important to my productivity, after making phone calls, is to
a) View my contact and calendar info on my iPhone (vs only on my laptop)
b) Sync my contact and calendar info with changes I make during the day between my laptop and my iPhone to Outlook 2010.
To accomplish that as well as having a total backup of my iPhone with high integrity, I thought both 1) and 2) would be necessary.
I do value reliable backups. I rotate 2TB backup drives of my home system through my safe deposit box several times/year for off-site backup in event of fire, theft, natural disaster, etc..
If both my laptop and home PC are authorized in iTunes, and if, on my home PC, I have all the iTunes boxes checked to sync, shouldn't that work as my most trusted iPhone backup?
people with tiny hard drives in their laptops i guess, why dont you just sync everything with the desktop
Because when I travel, I only have my laptop and iPhone. My home PC is too heavy to carry with me.
I do want to sync everything with my home PC so that I have a complete backup. But 99% of the time, I'm using the contact and calendar info on either my iPhone or my laptop. Not my home PC.
PS just curious what size hard drive do you actually have in that laptop
128gb.
On that drive I've deleted everything but work files, iTunes / my iPhone backup, and Quicken. I even deleted my remaining album on my laptop, One Eskimo.
I needed to trade in my favorite 15" heavy laptop with more than enough storage for my current 11.5" lightweight for the same reason I needed to switch to an iPhone from a Blackberry --
I OD'd on pressing Blackberry keys, and last year needed to have my thumb joint replaced. First symptom beyond pain when texting was closing a zip-loc back started to feel like a lightning bolt was hitting my thumb joint. I never knew what bone-hitting-bone pain felt like... Surgery went fine, recovery and PT were painful (picture the thumb cast coming off, then moving clothespins of varying resistance from one dowel to another with thumb and forefinger...) But now it works perfectly and I can even squeeze toenail clippers hard enough with that thumb as of last month.
So now I tap instead of press, and I don't pick up my laptop using only my thumbs and fingertips. Surgeon said if laptop weighs 1lb, picking it up with thumb and finger tips puts 10lbs of pressure on your thumb joint, vs only 3lbs if you put more of it into your hand web before picking it up.
Overall I like the experience of using an iPhone much better. It's more fun, more personal. Of course better apps.
But using iTunes makes me feel like I'm wearing handcuffs. I don't trust it. I would never use it as the place where I keep my music. It seems like it could easily all go poof.
