Despite early doubts about Research In Motion's BlackBerry PlayBook, analysts now say the tablet had a good showing in its first month on the market.

The debut tablet from RIM first became available last month. Though the PlayBook had a lot of hype behind it, it hit the market to mixed reviews.

However, according to RBC analyst Mike Abramsky, the tablet has posted "steady" sales numbers since its debut, selling approximately 250,000 units in its first month. While these figures pale in comparison to the first-day sales of Apple's iPad, Abramsky stated that the PlayBook sold more than the Android-based Motorola Xoom, which came out in February.

While the 7-inch PlayBook has struggled to find favor, some experts have said that as more capabilities and tablet accessories are introduced, it may eventually become a serious contender for the untapped enterprise tablet market.

According to a recent Gartner report, Apple's iPad will dominate tablet market for the foreseeable future, capturing more than 50 percent of the total market share until 2015.
