We found that out the hard way. Not that I think a tablet can replace a desktop computer, but for the limited stuff my wife does I thought a tablet was ideal.
Then she lost her job and for some government website she had to regularly fill in some form and send it. That website didn't work on the ipad (or any mobile device for that matter). Another website she needed required her to regularly upload a document. This doesn't work as you can't browse for files to upload on a mobile device.
We sold the ipad and she's back on a regular laptop.
That's exactly the sort of problems that people I know have run into, and part of the reason I don't recommend an iPad for anyone if they don't have a computer. It seemed like they could potentially be a good alternative these days, and there are ways to work around some of the limitations, but it's still a very restricted device overall.
The thing that annoys me the most, is that Apple have essentially replaced their "low-end" notebook line with them. About five or six years ago, we bought a pair of the original 13" MacBooks and they were equivalent to about $850. (Apple gear has always been more expensive here)
The cheapest MacBook you can buy today is the 11" air, which is equivalent to ~$1350 here.
The cheapest 13" notebook - because 11" is too small - is ~$1500, approaching double the price of the machines we are looking to replace.
In the end we bought a 13" Retina MacBook Pro, because the specs of the 13" Air just didn't seem to justify the cost, and the price gap wasn't that large, relative to the difference in performance and features.
We still haven't done anything about replacing the second MacBook - they want to get an iPad mini, but I
know it - or a full size iPad - won't be a suitable replacement.
Nothing will ever replace anything.
Desktops, laptops, tablets and phones. All have their place.
Notice that you didn't mention netbooks there at all.
I'm not saying you're wrong, and for some people, maybe a tablet really
is all they need - for me, I just find that my iPad is getting less and less use now, and its limitations are becoming far more apparent the longer I have the device.
But with Haswell notebooks being available in
similar form-factors (if you consider an 11" MBA to be similar) with almost the same level of battery life, I can see them taking back some of the marketshare that the iPad took away. One of the main motivations for me buying an iPad originally was the 10 hour battery life, and portable form-factor, compared to the 13" MacBook Air which was quite a bit larger and only had ~3 hours of real battery life at the time.
I switched to Feedly on my iPad and Win 8 system and am very pleased.
The problem is that I don't like the "magazine style" RSS presentation that is popular today (it's too slow once you have more than a handful of feeds) and Reeder was
by far the best RSS app around for the way that I like to read & manage feeds, as I was able to filter things out quickly, and it did a nice job presenting the content. I haven't found another reader on any platform that I like nearly as much.
v2 is in development and will support syncing to other services, but they should have had an app out in time for Reader shutting down. They only updated the mobile version, and not the tablet or desktop versions.
I'll check out Feedly, but what I have found over the last month or so is that I tend to still come across anything which is actually "important" news that I would have been reading via RSS anyway, and a lot of the blog style feeds I followed have stopped updating recently, so I'm thinking that maybe I just don't need RSS in my life any more - which means I probably don't nee the iPad any more, as that's what I was mostly using it for.
