With the rise and fast fall of MetroTube in the Marketplace, SuperTube for many was and still is the best alternative. For those of you set on MetroTube though, you'll want to take a gander at the new overhauled SuperTube app called YouTube Pro, which is currently in beta. We'll be curious if that app name sticks but regardless, we're more interested in the way it looks and performs.
We've been using Beta 2 for a few days now and are quite pleased. Live Tiles for your subscriptions, push notifications, background downloading, video uploading, low quality (LQ)/high quality (HQ) and high definition (HD) playback--this app has it all.
No word on release or pricing but we don't think it'll be too much longer. So fret not, YouTube lovers, you have another alternative.
For now, you can try the current version of SuperTube which will run you a cool $1.29 in the Marketplace, or you can get the free ad-supported version here
