Google to the rescue with the numbers etc...I always just ask the person whose number I want to call my number, not answer it, and then just give it a name and it'll stay in Google Contacts forever and be available on all devices and platforms. I don't even save contacts on my phone any more, no need. They're all always synchronized anyway. With any luck the other guy or gal is a Google user also and I get the addresses and all too. Gmail is my primary method for saving important info too; I may send stuff to myself from my phone for instance quite often. Like taking a quick snapshot from an address or piece of information and it'll go directly to Gmail. I delete all my 'unnecessary' email as I get it, usually from my phone, but anything that might have something useful is in gmail and will stay there. Then I can just quickly search for it directly from any device.
I guess one reason I don't use texting much is that while my company gave me a work telephone, it's just a cheap junker of a phone, so I NEVER use it, I mean, I do my work calls on my phone almost always...well sometimes I might use the work phone to call someone, because that's what it's for...so I don't have to pay for work calls myself...but I rather pay than use that junker. Now, I have call forwarding always on so when I get work calls, they are redirected to my personal phone, but the catch is texts messages are NOT forwarded, plus now I have to actually pay for work calls I get. But it's like $10 a month at worst so no matter. But...I may not even open my work phone for weeks and sometimes I miss some texts because of that. I just keep it in the charger on the table and it gets lost under the papers there for long times.
Bloody annoying at work that BTW they won't give me a proper phone...if it were even an iPhone I'd probably use it. Anything, but it's just a normal old-style cell. Probably costs under $20.
But that's the trend...I had to fight for two years to get a laptop instead of desktop at work...and when I finally got it, they'd only give me a 19" external display, which I refused. I've been trying to get at least 24" for external display, or I won't accept any. Rather just use the laptop's own display. Also had to buy a laser printer before they arranged for mobile printer connections, and I tried to get a scanner but had to buy my own anyway, as I did an external drive for backups etc. Also for mobile connection they only gave me a measly 512K 3G connection so I got me a 21MB 4G connection with my own expense so I can use YouTube videos etc. in class from my laptop which is always hooked to the class video projector or smartscreen.
Been thinking of installing an SSD drive on my work laptop too at my own expense...it's strictly forbidden to do such mods to these leased machines but I'm on good grounds with the IT folk...and they gave me admin rights to the machine so I could just clone the disk and nobody would notice

but this is a pretty fast i5 laptop anyway so maybe not. If I happen to have a spare SSD some of these days I might, but won't buy one for just that use.
