I have both - a Mac & a HP laptop so I can switch between them... the HP is even slower that my mac at everything, so I'm just having to get used to it.
I laugh everytime I hear of the Govt's policy of every home having access to "high speed internet"... we don't even had mains sewerage ffs... our electricity goes off once a month and gas... the only gas we have in from the cows in the front field! Since I signed an 18 mth deal with my ISP my speed has halved! NOT impressed!!!
But yeah, you're right, if you're the only one with a Mac its a bit pointless if you can't share the software.
