i did have one of those battery packs. theyre great, but the samsung batteries(well the older samsungs) are easily removed. they cost $20 and ive got 3 . So i charge all those batteries up before going on a big sail and i dont have to worry about doing any charging while underway. Im using navionics, playing music etc through the phone so it chews through the juice.
It seems that every new bit of tech that comes out , be it computer operating systems, new phones , computers, nbn - they come out less and less user friendly.
I use an older os version on my mac computers . os10.6.8. snow leopard. I did upgrade to the latest a while back but simple features vanished. the os became unusable to me so i reverted back. Now the problem is browsers/programmes superseeding my os so im limited by this.
Ive just had no phone for the last 3 days. it is possible. what a great feeling. my clients all email me and i can call my message bank from skype to check any messages. It can be done!
