The thing about Slicehost, and I just had this convo on #startups, is that they can move you to metal when you get too big for your britches. Also, Linode's biggest box is 2G, which is a serious upper limit.
I know you're a mac guy, but you should look at Axure for prototyping. It's ill as all get out.
If you're targeting cheap, then Linode is a better bet - you get more for your money. There are plenty of options when you get bigger, but if you really need to save, then deal with getting big when it happens, rather than spend money on 64 bit pointers.
when you get much above 2gb, you should seriously start thinking about hardware. Especially at current market prices for a VPS, it's often cheaper to buy and host your own hardware once you get above the 2gb-4gb range. A core2duo 1u with 8GB ram? around $500-$600 for the hardware. Hosting for said 1u? as low as $50/month.
