I'm using a portable, and my wife's desktop, and my ISP makes it impossible to download the upgrades, anymore, if they are too big or i get to the limit (on the "unlimited" service we pay for) or the ISP's capacity limit. For whatever reason, this site still works for me. Hope the programmers, here, notice this and have the time to fix it. Are they volunteers, or pros doing it on their "off time"? Either way, we need to appreciate them. Tablets can be the only answer for some, due to needing smallest size or least inexpensive. Smart phone don't cut it when you need a computer and the programs made for computers. My fingers are too big for those touch screens, too.
Got a relative doing programing, maintaining websites, on his own time & dime, for two non-profits. Ain't easy. I've never seen (or tried enough to check out) how we operate, aside from doing the Charity Navigator thing. We aren't big enough, too low in "dollar income", to get the full evaluation, but that IRS form we send in looks good.
Two other things you might try. Walk into your ISP's office/store and ask to use their unlimited, super-fast access to get your upgrade. I had help on that. The other thing: sometimes you can walk into store of the manufacturer of your device and use their ISP or even get them to do it. I've had help a couple of times that way, but its a 180 mile drive, one way, for that. (I just happened to have to be in that city for something else. Nothing like killing 4 birds with 1 stone). But our phone/ISP store is a 20 mile drive in a town we go to several times a week. They almost know us by name!) The lines can be long, so i got in early morning or as late in the evening as i can get away with.
Good luck.
