Saving in general has become much less rewarding in recent years. The BOE doesn't want you to save, hence why interest rates are so low, and why you have made this thread 'ISA - whats the point'.
Who know's when interest rates will get back to 'normal' levels, but my guess is years and years.
In the meantime you have two option, suck it up and accept saving cash from an investment POV is pointless as rates are so low and inflation will prob jump back up again soon meaning even less real return.
Next option is what all investors are having to do, realize that in these times if you want decent returns on your investments, you are going to have to take more risk!
The last few years has been a great rally for the stock market, especially Stateside. Some people believe this rally is soon to end, but they lack a crystal ball, and there have been folk saying the bull run is going to end for years, it keeps going.
+1 for the S&S ISA, shelters you from capital gain, and tax on dividends.
