Trays are considered "old fashioned" these days, as they do not protect the coins from the atmosphere at all. If all your coins are well-circulated and non-lustrous, that's no big deal, but if you've got Proof, Unc or other lustrous coins, you'll want to protect them better than a tray.
The other drawback with trays is, once you take a coin out of the tray, you have to remember where you took it out from. This is fine if you only take your coins out one at a time; I'm more a "take dozens out all at once" sort of person. And on a related note, you don't want to be the clumsy sort; coins in a tray are totally unprotected from being dropped and scattered across the floor - which both damages the coins, and is a pain to re-sort again.
Lidner trays are great for coin dealers on the road, as they are a relatively quick and convenient transport method that also looks good from a customer's perspective. But for a collector, I'd seek a better option.

Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
