ixbrl problems

What do other accountants recommend for ixbrl.  I use sage accounts production, i only have 5 ltd companies.  I pay about £400 for support which i only use really for the ltd company accounts.  I had to get a new computer last year as it needed a 64 bit computer.  Now the new sage says there is not enough ram on this new computer and also sage will not support windows 7 home only windows 7 professional  The whole ixbrl thing is getting past a joke, software and hardware costs.  How difficult is it to use the inland revenue software?  How do you tag existing accounts??
