Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for speed. When latency is the product, start here.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
