I've had three - one a proper old lady tartan rectangular one with 4 wheels and a metal frame - the uber cool DD thought it was a genius idea and would volunteer to push it once the tartan insert had been removed (which I was fine with).
Then one with bird print from IKEA. That disintegrated in the end as it had such hard use.
Then a collapsible crate one - which was my favourite, mainly because it was exactly the right size to hold a practice amp for gigs. The last was stolen from outside the front door in the 30 seconds it took me to carry the £800 amp inside. So it was obviously appealing to somebody young enough to run round the corner with it even when empty. Bastard.
I'm now getting to the 'right age' to have one. I don't give a shiny shite about what anybody else thinks about it/me, it means less unnecessary plastic and, more importantly, no fucked up shoulder, back and elbows from carrying too much stuff home from the market. Environmentally friendly (well, more so than carrier bags or a car - can't afford a basket type one), less physical effort involved so good for being disabled, kids don't associate them with anything but not having to carry the potatoes home in a shitty plastic carrier that splits ten yards down the road or cuts into your hands with the five others you're already carrying to help Mum out - everyone's a winner.
DP staggered in from the shops a few months ago with heavy bags and said, once he had collapsed on the settee and whinged about how much his shoulders hurt, that we should really think about getting 'one of those shopping trollies, because Grandma had the right idea' when she'd get him to do her shopping with one when he was 16.
If it's acceptable to a 42 year old punk guitarist, I'm pretty sure everybody else can handle it.
