Tablets

I'm not really a fanboy, but I do keep a close eye on Apple.  Ever since the iPhone showed they had the right idea.  The trouble is, they don't seem to be doing much at the moment.
I got a new iPad this year.  To replace the original one I had.  I'd been saving up for the first one for some time (well before it's actual existence was admitted.)  After two years it was unusably unstable.  This was due to not having enough RAM in the first place.  So Apple abandoned it.  I couldn't find any better tablet though, so I had to replace it with the current model iPad.  Which had a higher resolution display.  Though my eyesight had deteriorated so much in the same time period that I couldn't tell the difference.  Sigh.
I seriously considered a Microsoft tablet.  But the Pro model was too expensive, and the RT model was a pointless exercise in trying to copy what Apple had done with iOS.  Poor Microsoft.  They had the right idea, but still messed up.  And now their boss is leaving.
Maybe I should have bought an Android one.  Or a Kindle.  The trouble is that I am so deep into Apple's ecosystem now that it's unlikely any one product will be enough to make me bail out.  Even given the inferiority of iPhones nowadays...
