Well, I haven't spent money on the Photography hobby for well over six years at this point, other than new batteries and a part to repair a broken lens (EDIT: oh, and a new kit bag). Yes, quite a bit back when I "went digital" but not since then (can't afford it).

Note that a year with a new smartphone would cost me about $1000 or so -- to purchase the phone and pay the monthly fees here in Canada. Ditto for an iPad with a mobile network account.

The 9-11 hours battery life on the netbook is with wifi and a read/write drive. The "ram disk trickery" or whatever makes little if any difference to battery life -- it's more of a quicker boot and safer run environment, but I don't use that any more.

0.65KG is lighter than my 1KG "netbook", and even more lighter than the iPad that I saw and handled here.

Cheers
